Question

The temperature difference between the inlet and the outlet
of an air-cooled engine is 30.0 K. The engine generates 7.0 kW
of waste power that the air extracts from the engine.
Calculate the rate of flow of air (in kg s-1) needed to extract
this power. Specific heat capacity of air (at constant pressure)
= 1.01 X 103 J kg-1 K-1.​

Answer 1

Answer:

he temperature difference between the inlet and the outlet

of an air-cooled engine is 30.0 K. The engine generates 7.0 kW

of waste power that the air extracts from the engine.

Calculate the rate of flow of air (in kg s-1) needed to extract

this power. Specific heat capacity of air (at constant pressure)

= 1.01 X 103 J kg-1 K-jeidHdi
