Formulas:
Vx = (R)Cosθ
Vy = (R)Sinθ
R2 = x2 + y2
TanΘ = y/x
Tan-1(y/x) = Θ

Air is to be preheated by hot exhaust gases in a cross-flow heat exchanger before it enters the furnace. air enters the heat exchanger at 95 kpa and 20°c at a rate of 0.6 m^3/s. the combustion gases (cp = 1.10 kj/kg°c) enter at 160°c at a rate of 0.95 kg/s and leave at 95°c. determine the rate of heat transfer to the air and its outlet temperature.
