Question

evaluate the availability of a system which absorbs 15mj of heat from a heat source maintained at 1000k while surrounding is at 300k​

Answer 1

Answer:

Explanation:

Given that,

Temperature T  1 =270K

Temperature T  2  =300K

Absorbed heat Q=1260KJ/min=21KJ/s

We know that,

Coefficient of performance is

C.O.P =  T  2 ​   −T  1​    T  2

C.O.P=  

300−270

270

​C.O.P=9

Using formula of work done

C.O.P=  W Q

W=  9 21

W=2.33KJ/s

The work required is2.33KJ/s.

Hence, This is the required solution.
