Please consider a stream of low pressure air that passed through a heat exchanger at a rate of 3.4 lbm/min. The air absorbed 1.15 kJ/min. Please determie the change in air tempature in K.. Show Work

Solution

1.15 kJ is transferred to 3.4 lbm air
Q = Cp×m×dt and dt = Q/Cp×m
dt = 1.15 kJ ÷ ( 1.005 kJ/kgK × 3.4/2.2) = .74 K
