An engine with liquid-cooled system uses a radiator to dissipateheat from the engine while it is operating. The coolan (Pure water)has a constant mass flow rate f 0.1 lbm/s. Enters the radiator as asaturated mixture with quality x = 0.1 and 20psia, and then leavesas saturated liquid at 20psia. If the air is standard atmosphericpressure and 540 R enters the radiator at 60mph, removing heat fromliquid coolant by flowing through the radiator. Assume the totalcross-section area for the air flow to be2ft^2.
a) What is the operating temperature of the liquid coolant inthe radiator (in Fahrenheit)?
b) What is the rate of the heat removal from engine block by thecoolant (Btu/s)?
c) What is the mass flow rate f the air through the radiator(lbm/s)
d) What is the temperature f the air at the outlet of theradiator (R and F)?
