The Brake-specific fuel consumption
(BSFC) of a diesel engine is 200 gm/kWh. If the calorific value of diesel is 40
MJ/kg, the brake thermal efficiency is:
डीजल इंजन की ब्रेक-विशिष्ट ईंधन खपत (BSFC) 200 ग्राम/किलोवाट है। यदि डीजल का ऊष्मीय मान 40 MJ/kg है, तो ब्रेक थर्मल दक्षता है:
31%
28.4%
39.4%
45%
45%
Given : Brake specific fuel
consumption, BSFC = 200 gm/kWh
Calorific value = 40 MJ/kg
Brake thermal efficiency
Hence, the correct option is (D).
