An engineer claims to have made an engine delivering 10 kW power with fuel consumption of `1gs^(-1)` . The calorific value of fuel is 2 k cal / g . His claim

A

valid

B

invalid

C

depends on engine design

D

dependent on load

Text Solution

Verified by Experts

The correct Answer is:
B
P=10kQ=10000 W
Fuel consumption =1g/s
Calorific value =2kcal/g
`therefore` Energy produced =2 kcal/s
Input power `therefore` This claim is valid.
