Answer:

"192.3 watt" is the right answer.

Explanation:

Given:

Efficient amplifier,

= 65%

or,

= 0.65

Power,

\(P_c=250 \ watt\)

As we know,

⇒ \(P_t=P_c(1+\frac{\mu^2}{2} )\)

By putting the values, we get

        \(=P_c(1+\frac{1}{2} )\)

        \(=1.5 \ P_c\)

Now,

⇒ \(P_i=(P_t-P_c)\)

        \(=1.5 \ P_c-P_c\)

        \(=\frac{P_c}{2}\)

DC input (0.65) will be equal to "\((\frac{P_c}{2} )\)".

hence,

The DC input power will be:

= \(\frac{250}{2}\times \frac{1}{0.65}\)

= \(\frac{125}{0.65}\)

= \(192.3 \ watt\)

The value of K that makes the steady-state error of the closed-loop system equal to 0.01 for both step and ramp inputs is approximately K = 26.27.

To determine the steady-state error of the closed-loop system, we first need to find the closed-loop transfer function.

The closed-loop transfer function of a system is given by:

Gcl(s) = Gs/(1 + GsHs)

where;

For this problem, we have a unity feedback system, so Hs = 1.

Substituting Gs in the above equation, we get:

Gcl(s) = K(s+3)/(s³ + 3s² + 2s + 3K)

Now, we can use the final value theorem to find the steady-state error of the system for a step and a ramp input. The final value theorem states that the steady-state value of the output y(t) is given by:

lim s->0 sY(s) = lim t->∞ y(t)

For a step input u(t) = U0, the steady-state error is given by:

ess = lim s->0 s(1 - Gcl(s))U0

Setting ess to 0.01, we get:

0.01 = lim s->0 s(1 - K(s+3)/(s³ + 3s² + 2s + 3K))U0

Solving for K, we get:

K = 26.27

For a ramp input u(t) = Ut, the steady-state error is given by:

ess = lim s->0 s²(1 - Gcl(s))U0

Setting ess to 0.01 and substituting Gcl(s), we get:

0.01 = lim s->0 s²(1 - K(s+3)/(s³ + 3s² + 2s + 3K))U0

Solving for K, we get:

K = 27.86

For Part A, the velocity of peg A when x = 1.2 m can be calculated using the equation v = s/t, where s is the distance traveled and t is the time taken. Since the link is moving at a constant speed of 10 m/s, the time taken to travel 1.2 m is 1.2/10 = 0.12 s.

Therefore, the velocity of peg A when x = 1.2 m is v = 10/0.12 = 83.33 m/s.

For Part B, the acceleration of peg A when x = 1.2 m can be calculated using the equation a = (v2 - v1)/t, where v2 and v1 are the velocities of the peg at the two different points and t is the time taken to travel between them. Since the link is moving at a constant speed of 10 m/s, the time taken to travel 1.2 m is 0.12 s.

Therefore, the acceleration of peg A when x = 1.2 m is a = (83.332 - 102)/0.12 = -833.33 m/s2.

Explanation:

Option A

Both Technician A and Technician B are correct. Option C

The DPF's pressure differential sensor (delta-P sensor) plays a crucial role in the exhaust DPF's regeneration process. It measures the difference in pressure between the inlet and outlet of the DPF, which indicates the amount of soot accumulation in the filter.

This information is used to initiate the regeneration process by injecting fuel into the exhaust system to increase the exhaust temperature and burn off the accumulated soot.

However, Technician B is also correct in saying that the amount of soot loading is estimated and not accurately measured using the delta-P sensor.

The sensor provides an estimate of the soot accumulation based on the pressure difference, but it does not directly measure the actual amount of soot. Other factors such as the engine's operating conditions and the quality of the fuel can affect the accuracy of the estimation.

The delta-P sensor is essential for the regeneration process, but it provides an estimated value of the soot accumulation rather than an accurate measurement.

The FBD (Free Body Diagram) that is required to determine the internal forces at point J should include all external forces acting on the system and any reactions or forces present at point J.

This FBD will allow for the determination of the internal forces, such as shear forces and bending moments, at point J.
To determine the internal forces at point J, you need to draw a Free Body Diagram (FBD). In this FBD, you should include all the external forces acting on the object at point J, such as gravitational force, tension, friction, and any applied forces. Once you have drawn the FBD, you can use equilibrium equations (sum of forces in horizontal and vertical directions equals zero) to solve for the unknown internal forces. After finding the internal forces at point J, you can move on to the next part of your problem. Forces are physical quantities that describe the interactions between objects or systems. They can cause a change in motion or deformation in an object. Some common types of forces include gravitational force, electromagnetic force, frictional force, and normal force. Forces can be described by their magnitude, direction, and point of application. Newton's laws of motion provide a framework for understanding the behavior of objects under the influence of forces. Understanding forces is essential in many fields, including physics, engineering, and biomechanics, as it allows for the prediction and control of the behavior of systems under different conditions.

The combined design water capacity of the water treatment facility and distribution system should be 19,221,000 litres per day.

Maximum Day Demand (MDD) x 1.80 W3-01.3 System Parameters = Peak Hour Demand (PHD). A. Average Day Demand (ADD) multiplied by 2.25 to get Maximum Day Demand (MDD).

Average water demand = Population x Average water demand per capita

Average water demand = 55,000 x 170 liters per capita per day

Average water demand = 9,350,000 liters per day

Maximum day water demand = 1.5 x 9,350,000 liters per day

Maximum day water demand = 14,025,000 liters per day

Peak hour water demand = 170 liters per capita per day x 55,000 people x 2 / 24 hours x 4 peak hours

Peak hour water demand = 9,067 liters per hour

Fire demand = 3 liters per second x 60 seconds per minute x 24 hours

Fire demand = 5,400 liters per day

Design water capacity = 14,025,000 liters per day + 5,400 liters per day + (0.2 x 9,350,000 liters per day)

An environmental hazard is a substance, state or event which has the potential to threaten the surrounding natural environment and/or adversely affect human's health. This term incorporates topics like pollution, natural disasters and human-made hazards. Health studies investigate the human health effects of exposure to environmental hazards ranging from chemical pollutants to natural, technological or terrorist disasters. The environment in which we live can be considered as having three fundamental sets of components, physical, chemical, biological. Associations between an exposure and an adverse health effect do not, on their own, prove that the former is the cause of the latter. Many other non-causal associations could explain the findings. Physical hazards involve environmental hazards that can cause harm with or without contact. Examples are earthquakes, electromagnetic fields, floods, light pollution, noise pollution, vibration, x-rays etc. Radioactivity is associated with an exposure dependent risk of some cancers notably leukaemia. The scientific evidence of adverse health effects from general environmental exposure to these fields is "not proven". If there are adverse effects yet to be proven, the risk is probably likely to be small. Chemical substances cause significant damage to the environment. Tobacco smoke is the single biggest known airborne chemical risk to health, whether measured in terms of death rates or ill-health. To a much lesser degree of risk, these adverse effects apply to non-smokers exposed passively to sidestream tobacco smoke. Health effects of concern are asthma, bronchitis, lung cancer and similar lung diseases, and there is good evidence relating an increased risk of symptoms of these diseases with increasing concentration of Sulphur dioxide, ozone and other pollutants. Biohazards generally fall into two broad categories: those which produce adverse health effects through infection (microorganisms, viruses or toxins) and those which produce adverse effects in non-infective (allergic) ways.

Answer:

± 0.003 ft

Explanation:

Since our distance is 10,000 ft and we need to use a full tape measure of 100 ft. We find that 10,000 = 100 × 100.

Let L' = our distance and L = our tape measure

So, L' = 100L

Now by error determination ΔL' = 100ΔL

Now ΔL' = ± 0.30 ft

ΔL = ΔL'/100

= ± 0.30 ft/100

= ± 0.003 ft

So, the maxim error per tape is ± 0.003 ft
