The radiator of a car is a heat exchanger that uses air to cool the coolant (assume water) from the engine. The heat that must be transferred to the air is 150 kW and the coolant experiences a 10 C change in temperature as it passes through the radiator. Air enters the radiator at 30 C and 100 kPa and exits at 100 C and 100 kPa.
A) What is the mass flow rate of coolant through the radiator? (kg/min)
B) What is the volume flow rate of the air at the inlet to the radiator? (m^3/min)
