A 90-hp (shaft output) electric car is powered by an electric motor mounted in the engine compartment. If the motor has an avera
pantera1 [306]

Answer:

Heat supply rate is measured at 8.901 horsepower.

Explanation:

Energy efficiency of the electric vehicle, as per Thermodynamics (\eta), is the proportion of translational mechanical power (\dot E_{out}), expressed in horsepower, and electrical energy (\dot E_{in}), also in horsepower. The heat supply rate (\dot E_{l}), indicated in horsepower, that the motor delivers to the engine bay under full load can be determined by subtracting the translational mechanical energy from the electric energy. This is expressed as:

\eta = \frac{\dot E_{out}}{\dot E_{in}} (1)

\dot E_{l} = \dot E_{in}-\dot E_{out} (2)

\dot E_{l} = \left(\frac{1}{\eta}-1\right)\cdot \dot E_{out} (3)

If we have the values of \eta = 0.91 and \dot E_{out} = 90\,hp, the heat supply rate can be calculated as:

\dot E_{l} = \left(\frac{1}{0.91}-1 \right)\cdot (90\,hp)

\dot E_{l} = 8.901\,hp

The heat supply rate amounts to 8.901 horsepower.

Compute the sum with carry-wraparound (sometimes called the one's complement sum) of the following two numbers. Give answer in 8
grin007 [323]

Response:

00100111

Explanation:

We have been given;

10010110

10010000

Add them following standard binary addition rules

10010110

10010000

-------------

(1)00100110

-------------

ignore the leading (1) because it is a carry.

Increase the result by 1 to achieve a 1's complement sum

00100110 + 1 = 00100111

Final Result: 00100111

A hydraulic cylinder is to be used to move a workpiece in a manufacturing operation through a distance of 50 mm in 10 s. A force
Viktor [391]

Response:

The solution to this question is 1273885.3 ∅

Clarification:

The first step is to ascertain the required hydraulic flow rate liquid based on the working pressure if a cylinder with a piston diameter of 100 mm is utilized.

Given that,

The distance = 50mm

The time t =10 seconds

The force F = 10kN

The piston diameter = 100mm

The pressure = F/A

10 * 10^3/Δ/Δ

P = 1273885.3503 pa

Subsequently

Power = work/time = Force * distance /time

= 10 * 1000 * 0.050/10

which amounts to =50 watt

Power =∅ΔP

50 = 1273885.3 ∅
