A brine solution is 26% salt with 70.0 kg of water evaporated per hour. To produce 195 kg of pure salt (0% moisture) per day, how long should the process operate each day and how much brine must be fed to the evaporator per hour?
The process should operate each day for ___ hours.
The amount of brine that must be fed to the evaporator is ___ kg/h.

Answers

Answer 1

Answer:

- the process should operate each day for 7.9286 hours

- the amount of brine that must be fed to the evaporator is 94.594 kg/hr

Explanation:

Given that;

concentration of brine = 26%

so water concentration will be 100% - 26% = 74%

for evaporation of 70kg water per hour, residual is pure salt( 0% moisture)

so mass flow rate of brine = 70/(74%) = 70/0.74 = 94.5945 kg/hr

Amount of pure dry salt produced(0%) = 94.5945 - 70 = 24.5945 kg/hr

Now for production of 195kg of pure dry salt, number of hours required will be

T = 195 / 24.5945 = 7.9286 hrs

Therefore the process should operate each day for 7.9286 hours.

Total brine solution required ( 26% salt conc.) = 195/0.26 = 750 kg

Feed rate of brine solution ( 26% salt conc.) = 750 / 7.9286 = 94.594 kg/hr

Therefore the amount of brine that must be fed to the evaporator is 94.594 kg/hr

Which of the following devices has high resistance in the dark and low resistance when exposed to light

Answers

Photoresistors, also known as light dependent resistors (LDR), are light sensitive devices most often used to indicate the presence or absence of light, or to measure the light intensity. In the dark, their resistance is very high, sometimes up to 1 MΩ, but when the LDR sensor is exposed to light, the resistance drops dramatically, even down to a few ohms, depending on the light intensity. LDRs have a sensitivity that varies with the wavelength of the light applied and are nonlinear devices. They are used in many applications, but this light sensing function is often performed by other devices such as photodiodes and phototransistors. Some countries have banned LDRs made of lead or cadmium over environmental safety concerns.

Answers

Without additional information, it is not possible to determine the correct VOR indication.

Which VOR indication would be correct when the VOR is tuned to Jamestown VOR and the aircraft is positioned over Cooperstown Airport?

The accuracy of VOR indications depends on the specific location and alignment of the aircraft in relation to the VOR station.

The VOR indicator provides the aircraft's radial position relative to the VOR station, which can be used for navigation.

However, to determine the correct VOR indication, the specific radial and distance from Jamestown VOR to Cooperstown Airport, as well as the current position and heading of the aircraft, would need to be considered.

The boost converter of Fig. 6-8 has parameter Vs 20 V, D 0.6, R 12.5 , L 10 H, C 40 F, and the switching frequency is 200 kHz. (a) Determine the output voltage. (b) Determine the average, maximum, and minimum inductor currents. (c) Determine the output voltage ripple. (d) Determine the average current in the diode. Assume ideal components.

Answers

Answer:

a) the output voltage is 50 V

b)

- the average inductor current is 10 A

- the maximum inductor current is 13 A

- the maximum inductor current is 7 A

c) the output voltage ripple is 0.006 or 0.6%V₀

d) the average current in the diode under ideal components is 4 A

Explanation:

Given the data in the question;

a) the output voltage

V₀ = V\(_s\)/( 1 - D )

given that; V\(_s\) = 20 V, D = 0.6

we substitute

V₀ = 20 / ( 1 - 0.6 )

V₀ = 20 / 0.4

V₀ = 50 V

Therefore, the output voltage is 50 V

b)

- the average inductor current

\(I_L\) = V\(_s\) / ( 1 - D )²R

given that R = 12.5 Ω, V\(_s\) = 20 V, D = 0.6

we substitute

\(I_L\) = 20 / (( 1 - 0.6 )² × 12.5)

\(I_L\) = 20 / (( 0.4)² × 12.5)

\(I_L\) = 20 / ( 0.16 × 12.5 )

\(I_L\) = 20 / 2

\(I_L\) = 10 A

Therefore, the average inductor current is 10 A

- the maximum inductor current

\(I_{Lmax\) = [V\(_s\) / ( 1 - D )²R] + [ V

given that, R = 12.5 Ω, V\(_s\) = 20 V, D = 0.6, L = 10 μH, T = 1/200 kHz = 5 hz

we substitute

\(I_{Lmax\) = [20 / (( 1 - 0.6 )² × 12.5)] + [ (20 × 0.6 × 5) / (2 × 10) ]

\(I_{Lmax\) = [20 / 2 ] + [ 60 / 20 ]    

\(I_{Lmax\) = 10 + 3

\(I_{Lmax\) = 13 A

Therefore, the maximum inductor current is 13 A

- The minimum inductor current

\(I_{Lmax\) = [V\(_s\) / ( 1 - D )²R] - [ V

given that, R = 12.5 Ω, V\(_s\) = 20 V, D = 0.6, L = 10 μH, T = 1/200 kHz = 5 hz

we substitute

\(I_{Lmin\) = [20 / (( 1 - 0.6 )² × 12.5)] - [ (20 × 0.6 × 5) / (2 × 10) ]

\(I_{Lmin\) = [20 / 2 ] -[ 60 / 20 ]    

\(I_{Lmin\) = 10 - 3

\(I_{Lmin\)  = 7 A

Therefore, the maximum inductor current is 7 A

 

c)  the output voltage ripple

ΔV₀/V₀ = D/RCf

given that; R = 12.5 Ω, C = 40 μF = 40 × 10⁻⁶ F, D = 0.6, f = 200 Khz = 2 × 10⁵ Hz

we substitute

ΔV₀/V₀ = 0.6 / (12.5 × (40 × 10⁻⁶) × (2 × 10⁵) )

ΔV₀/V₀ = 0.6 / 100

ΔV₀/V₀ = 0.006 or 0.6%V₀

Therefore, the output voltage ripple is 0.006 or 0.6%V₀

d) the average current in the diode under ideal components;

under ideal components; diode current = output current

hence the diode current will be;

\(I_D\) = V₀/R

as V₀ = 50 V and R = 12.5 Ω

we substitute

\(I_D\) = 50 / 12.5

\(I_D\) = 4 A

Therefore, the average current in the diode under ideal components is 4 A

Ew Wakefield Hospital has only one portable X-ray machine. The emergency room staff claim to have the greatest need for the machine, but the surgeons in the operating room demand ready access to the machine. The conflict between these two groups is a result of scarcity.

Science and technology are the driving forces behind today's modern medicine, allowing us to identify and treat a range of medical problems. X-ray technology has had a significant impact on medicine, and it is commonly used to diagnose various diseases, making it an essential tool for hospitals.

Despite the advantages, the scarcity of portable X-ray machines creates difficulties for hospital employees, including a dispute between the emergency room and the operating room staff at Ew Wakefield Hospital. There is only one portable X-ray machine available at Ew Wakefield Hospital.

The conflict between the emergency room and the operating room staff is a result of scarcity. Both departments require ready access to the X-ray machine. Scarcity can generate rivalry, competition, and conflict when people and organizations compete for the same resource.

The staff's conflict is a direct result of the lack of accessibility to the X-ray machine. Thus, scarcity can be a significant factor contributing to interpersonal conflict.

Determine the range of values for the magnitude of P so that magnitude of the resultant force does not exceed 2500N. Force P is always directed to the right.​

Answers

The range of of values for the magnitude of P is 1886.370 N < P < 2186.354 N.

How to calculate the magnitude of the force?

In accordance with Newton's Second Law of Motion, the force acting on this car is equal to the horizontal component of the force (Fx) that is parallel to the slope:

Fx = mgcosθ

Fx = Fcosθ

Where:

F represents the force.m represents the mass of a physical object.g represents the acceleration due to gravity.

For the magnitude of P in the x-axis, we have the following:

∑Fx: FRx = P + 600cos45 - 1500cos75

       FRx = P + 36.0355

For the magnitude of P in the y-axis, we have the following:

∑Fy: FRy = 1500sin45 + 600sin75

       FRy = 1640.2156

Now, we can determine the range of of values for the magnitude of P:

\(F_R=\sqrt{(P + 36.0355)^2 +1640.2156^2} \le 2500^{2}\)

Below are listed parameters for different direct-mapped cache designs: Cache Data Size: 32 KiB Cache Block Size: 2 words Cache Access Time: 1 cycle Generate a series of read requests that have a lower miss rate on a 2 KiB 2-way set associative cache than the cache listed above. Identify one possible solution that would make the cache listed have an equal or lower miss rate than the 2 KiB cache. Discuss the advantages and disadvantages of such a solution.

Answers

To generate a series of read requests that have a lower miss rate on a 2 KiB 2-way set associative cache, we need to consider the cache parameters and access patterns. Let's analyze the cache listed above first:

Cache Data Size: 32 KiB

Cache Block Size: 2 words

Cache Access Time: 1 cycle

To reduce the miss rate on a 2 KiB 2-way set associative cache, we can consider the following factors:

Cache Size: The size of the cache affects its capacity to store data. Since the 2 KiB cache is smaller than the 32 KiB cache listed above, it may result in a higher miss rate. To generate read requests with a lower miss rate, we can focus on utilizing the available cache space efficiently.

Cache Block Size: The block size determines the amount of data fetched from memory into the cache on a cache miss. A larger block size can improve spatial locality and reduce miss rates. However, it can also lead to more capacity misses if the cache is not large enough to hold multiple blocks from the same memory region.

Access Patterns: The pattern of memory accesses can greatly impact cache performance. Sequential and localized access patterns tend to have lower miss rates compared to random or scattered access patterns. By designing read requests that exhibit good spatial and temporal locality, we can improve the cache's hit rate.

One possible solution to make the listed cache have an equal or lower miss rate than the 2 KiB 2-way set associative cache is to increase its associativity. The given cache is direct-mapped, meaning each memory block can only map to one specific cache block. By making the cache set associative (e.g., 2-way set associative), each memory block can map to two cache blocks instead. This allows for more flexibility in caching data and reduces the likelihood of capacity misses.

Advantages of increasing cache associativity:

Reduced miss rate: The cache can accommodate more data with increased associativity, improving the hit rate and reducing cache misses.

Improved spatial locality: Higher associativity allows for better utilization of cache space, increasing the likelihood of neighboring memory blocks being present in the cache.

Disadvantages of increasing cache associativity:

Increased complexity and cost: Higher associativity requires additional hardware, such as additional cache lines and comparators, which increases the complexity and cost of the cache design.

Increased access latency: The cache access time may increase due to the additional hardware and the need for more complex cache indexing and replacement policies.

It's important to note that the actual impact on the miss rate and cache performance depends on the specific access patterns and characteristics of the workload. Analyzing the workload and considering factors such as cache size, block size, and associativity can help in designing an optimized cache system with a lower miss rate.
