Determine the work done by an engine shaft rotating at 2500 rpm delivering an output torque of 4.5 N.m over a period of 30 secon

balu736 [363]

Answer:

work done= 2.12 kJ

Explanation:

Given

N=2500 rpm

T=4.5 N.m

Period ,t= 30 s

$torque =\frac{power}{2\pi N}$

$power=2\pi N\times T$

P= $2\times \pi \times2500 \times 4.5$

P=70,685W

P=70.685 KW

power= $\frac{work done}{time}$

work done = power * time

= 70.685*30=2120.55J

= 2.12 kJ

An inventor claims to have developed a food freezer that at steady state requires a power input of 0.25 kW to extract energy by

Snowcat [4.5K]

Answer:

The claim is false. ( $COP_{real} > COP_{ideal}$ ).

Explanation:

The real coefficient of performance of the food freezer is:

$COP_{real} = \frac{\dot Q_{L}}{\dot W}$

$COP_{real} = \frac{3\,kW}{0.25\,kW}$

$COP_{real} = 12$

The ideal coefficient of performance, that is, when freezer has a reversible process, is:

$COP_{ideal} = \frac{T_{L}}{T_{H}-T_{L}}$

$COP_{ideal} = \frac{270\,K}{293\,K-270\,K}$

$COP_{ideal} = 11.739$

A real freezer has a coefficient of performance lesser than or equal to ideal coefficient of performance. Since supposed real coefficient of performance is greater than ideal coefficient of performance. The claim is proved to be false.
