- Homework Statement
- "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. Specifc heat capacity of air (at constant pressure)
= 1.01 × 10^3 J kg–1 K–1 "
- Relevant Equations
- power/specific heat capacityXtemperautre
Frankly, i don't even know how to start this. I deducted from the solution, that they must have used power/(specific heat capacity x temperautre), however i don't understand how that will give the rate of flow of air. Could anybody help, please?
