Consider a rectangular fin that is used to cool a motorcycle engine. the fin is 0.2 m wide (in the flow direction) and at a temperature of 225°c, while the motorcycle is moving at 80 km/hr in air at 27°c. the air is in parallel flow over both surfaces of the fin, and you can assume fully turbulent flow (a) what is the rate of heat removal per unit length of the fin? (b) plot the heat removal rate per unit length as a function of the motorcycle speed from 10 to 100 km/hr.
