A sports car engine delivers 150 kW to the driveshaft with a thermal efficiency of 20%. The fuel has a heating value of 35 000 k
Andreyy89

Answer:600 kW

Explanation:

Given

Power delivered P=150 kW

Fuel heating value q=35,000 kJ/kg

thermal Efficiency \eta =\frac{Power}{Heat}

0.2=\frac{150}{35,000\times \dot{m}}

where, \dot{m} =mass\ flow\ rate\ of\ fuel

\dot{m}=\frac{150}{35,000\times 0.2}

\dot{m}=0.0214 kg/s

For an Engine

q\dot{m}=P+Q_r , where Q_r=heat\ rejected

Q_r=q\dot{m}-P

Q_r=750-150=600 kW
