Brake thermal efficiency of a 15 kW IC
engine is 30%. If the fuel used has CV 40 MJ/kg, then fuel consumption rate in
kg/h is :
15 किलोवाट आईसी इंजन की ब्रेक थर्मल दक्षता 30% है। यदि प्रयुक्त ईंधन में CV 40 MJ/kg है, तो kg/h में ईंधन खपत दर है:
2.5
4.5
3
1
4.5
Given : Brake thermal efficiency 
30%
Brake power (BP) = 15 kW
Calorific value of fuel (CV) = 40 MJ/kg
Hence, the correct option is (B).
