What are the input and output signals of the blocks in the block diagram, and what are the tasks of each box in terms of signal processing?

The logical network of the boxes in the block diagram involves the use of MSI circuits, such as the 4-bit parallel adder, 4-bit cascadable comparator, and 4-bit 7416x binary up-counter, along with the necessary number of logic gates and flip-flops. The input signals of the blocks in the block diagram include the clock signal, control signals, and data signals. The clock signal is used to synchronize the operations of the counter, while the control signals determine the specific sequence and timing of the output values. The data signals represent the binary values that are processed and propagated through the counter.

The tasks of the boxes in the block diagram involve performing specific operations on the input signals to generate the desired output sequence. For example, the 4-bit parallel adder can be used to increment the binary count by one, while the cascadable comparator can be utilized to compare the current count with predefined values to trigger specific actions. The 7416x binary up-counter can be employed to maintain the count and propagate it to subsequent stages.

In addition to these MSI circuits, logic gates such as NAND, NOR, AND, OR, XOR, and XNOR, as well as flip-flops like SR, JK, D, and T, are used to implement the necessary logic operations and sequential behavior within the counter.

Answers

Assuming complementary inputs are available, the minimum number of transistors needed to realize a two input xor gate is 4.

If two inputs work well together in the production process, they are said to be complements. Since the inputs are used in fixed proportions, if the price of one input lowers, more of it will be sought after, increasing the demand for the other input.

In this study, a model of anticompetitive exclusive contracts with complimentary inputs is built. A downstream company converts a variety of complementary inputs into finished goods. When complementary input providers hold a dominant position in a specific input market, upstream competition price within that market benefits both the downstream firm and the complementary inputs providers by driving up complementary input prices.

Thus, even when entry that is socially optimal is permitted, the downstream firm is unable to generate higher profits. Therefore, even in the absence of scale economies, downstream competition, and relationship-specific investment, the inefficient incumbent provider can prevent socially efficient entrance by employing exclusive contracts.

Determine an expression for the vorticity of the flow field described by V=−xy3^+y4^j Is the flow irrotational?

Answers

This problem can be solved using the pascal principle, which is applied for both pressures and volumes. In this case we use the definition of volumes, which says that the volume displaced fluid on one side of the Pistons should be equal to the volume displaced on the other side of the piston.

What is force?

The force exerted at the large piston will be double in magnitude in comparison with the force applied at the smaller piston.

We know, according to the pascal's law,

The pressure applied at any point in the incompressible fluid is equal in magnitude at each and every point.

So,

P = Force/Area

Where P is pressure,

If pressure is same, then we can write,

F₁/A₁ = F₂/A₂

Where,

F₁ is the force applied at the small piston,

A₁ is the area of the smaller piston,

F₂ is the force at the larger piston,

A₂ is the area of the larger piston,

It is also given that, area if the larger piston is two times the area of the smaller piston so,

A₂ = 2A₁

So, putting the values we get,

F₂/F₁ = 2

So, F₂ = 2F₁

It means that the force exerted by the larger piston will be double in magnitude.

Therefore, In this case we use the definition of volumes, which says that the volume displaced fluid on one side of the Pistons should be equal to the volume displaced on the other side of the piston.

A spherical tank with a radius of 0.25 m is filled with water (ρ = 1000 kg/m3). Calculate the mass and weight of the water in SI units.

Answers

The mass of the water is 65.5 kg. The weight of the water is 641.9 kgm/s²

What is the mass of a spherical tank?

The mass of a spherical tank is the space contained in the tank. The mass of the spherical tank can be determined by first finding the volume of the tank, then using the relation of density, mass, and volume to find the mass.

From the given parameter:

The radius of the tank = 0.25 mThe density of the water = 1000 kg/m³

The volume of the tank can be determined by using the formula:

\(\mathbf{V = \dfrac{4}{3}\pi r^3}\)

\(\mathbf{V = \dfrac{4}{3}\pi (0.25)^3}\)

V = 0.0655 m³

Using the relation that:

\(\mathbf{Density = \dfrac{mass}{volume}}\)

\(\mathbf{1000 \ kg/m^3= \dfrac{mass}{0.0655 \ m^3}}\)

mass = 1000 kg/m³ × 0.0655 m³

mass = 65.5 kg

The weight of the water can be determined by using the formula:

Weight = mass × gravity (i.e. acceleration due to gravity)

Weight = 65.5 kg × 9.8 m/s²

Weight = 641.9 kgm/s²

The mass of the water in spherical tank is 65.4kg.

The weight of the water in spherical tank is 640.8 Newtons.

Given the data in the question:

Radius of the spherical tank; \(r = 0.25m\)Density of water; \(p = 1000kg/m^3\)

Mass of water; \(m_w = \ ?\)

Weight of water; \(Ww = \ ?\)

Density

Density \(p\) is simply the measure of the compactness of the mass of a substance. It is expressed as;

\(Density = \frac{Mass}{Volume}\)

To determine the mass and weight of the water in spherical tank,

we calculate the Volume of the spherical tank.

\(V = \frac{4}{3}\pi r^3\)

We substitute in our given values

\(V = \frac{4}{3} * \pi * (0.25m)^3\\ \\V = \frac{4}{3} * \pi * 0.015625m^3\\\\V = 0.0654 m^3\)

Now, we calculate the mass of the water; using the expression above.

\(Density = \frac{Mass}{Volume}\\Mass = Density * Volume\\\)

We substitute in our values

\(Mass = 1000kg/m^3 \ *\ 0.0654m^3\\\\Mass = 65.4kg\)

Hence, the mass of the water in spherical tank is 65.4kg.

Next we calculate the Weight which is expressed as;

\(Weight = mass\ *\ Acceleration\ of\ gravity\)

Where acceleration of gravity \(g = 9.8m/s^2\)

We substitute in our values

\(Weight = 65.4kg * 9.8m/s^2\\\\Weight = 640.8kgm/s^2\\\\Weight = 640.8N\)

Therefore, the weight of the water in spherical tank is 640.8 Newtons.

a. 3.4
b. 14.3
c. 25.9
d. 67.7

Answers

Answer:

Weight Percentage of Ash = 3.4

Explanation:

Given - Coal containing 21% ash is completely combusted, and the ash is 100% removed in a water contact scrubber. If 10,000 kg of coal is burned per hour with a scrubber flow rate of 1.0 m3/min.

To find - the weight percentage of the ash in the water/ash stream leaving the scrubber is most nearly ?

Solution -

Given that,

Coal Burned Rate = 10,000 kg/hr

                              = \(\frac{10,000}{60 min} * 1 hr *\frac{kg}{hr}\)

                              = 166.6666 kg/min

⇒Coal Burned Rate = 166.6666 kg/min

Now,

Given that,

Ash content in coal = 21 %

⇒Ash in (coal that burned) = 166.6666 × \(\frac{21}{100}\) kg/min

                                             = 34.9999 ≈ 35 kg/min

⇒Ash in (coal that burned) = 35 kg/min

Now,

We know,

Density of water = 1000 kg/m³

Now,

Water flow Rate = \(1\frac{m^{3} }{min} * density\)

                           = 1000 kg/min

⇒Water flow Rate = 1000 kg/min

Now,

Total Mass flow Rate of (Water + Ash stream) = ( 1000 + 35) kg/min

                                                                           = 1035 kg/min

⇒Total Mass flow Rate of (Water + Ash stream) = 1035 kg/min

So,

Weight Percentage of Ash = (Weight of Ash ÷ Total weight of Stream) × 100

                                            = (35 ÷ 1035) × 100

                                            = 3.38 ≈ 3.4

∴ we get

Weight Percentage of Ash = 3.4

The change in the air's specific enthalpy during this process (kJ/kg) is -725 kJ/kg and there was definitely heat transfer involved in this process.

The initial temperature of air,

T1 = 1200 K

The final temperature of air,

T2 = 1800 K

The initial pressure of air

P1 = 100 kPa

The final pressure of air,

P2 = 2.3 MPa

We know that the change in the specific enthalpy is given by

:Δh = Cp ΔT + V(ΔP)

Where,Cp is the specific heat at constant pressureΔT is the change in temperatureV is the specific volume of airΔP is the change in pressureSince there is no information provided for the specific heats, let us assume them to be variable and evaluate the enthalpy changes by integration of Cp with respect to temperature..Therefore, option i. -725 kJ/kg is the correct answer to the first question. For the second question, it is very likely that there was heat transfer involved in this process, but this cannot be stated with certainty. Therefore, option b. It is very likely that there was heat transfer involved in this process, but this cannot be stated with certainty is the correct answer to the second question.

a load of 12tonnes is put along a horizontal plane by a force at 30°to and above the flat. if the coefficient of sliding friction is 0.2 find the frictional force​

Answers

Answer:

20368.917N

Explanation:

Frictional force (F) is the product of the Coefficient of friction and the normal reaction.

F = μN

Coefficient of friction, μ = 0.2

Normal reaction = MgCosθ

Mass, m = 12 tonnes = 12 * 1000 = 12000 kg

N = 12000 * 9.8 * cos30

N = 101844.58

F = 0.2 * 101844.58

F = 20368.917N
