Air Enters the radiator of a motor truck at a rate of 15 °C and at a rate of 240 m³/ min, and leaves the radiator at a temperature of

25 °C. If water circulates through the radiator at a rate of 50 L/min,calculate the temperature drop of the water. The specific volume of the air entering the radiator is0.8m3/kg. For water, assume C, = 4.19 kJ/kg K and p = 1000 kg/ m³ and for air, assume Cp = 1.005kJ/kg K
