Question

in a heatengine the temperature of the source and sink 700°c and50°c respectively the heat supplied 5mj/min what is maximum efficiency by the engine​

Answer 1

Answer:

Given,

T1=500K

T2=375K

Q1=25×105J

Efficiency of the engine,

η=1−T1T2

η=1−500375

η=1−0.75

η=0.25=25%

We know that, η=Q1W

W=ηQ1

W=0.25×25×105

W=6.25×105J

The correct option is A.
