a) A car sits outside all night. Use the model to predict for a cloudy day the winter warm-up transient, T' = T'(t), for 0 t 60 min for the following parameters: To' = 130F T' = 0F Qo=0 Vo' = 250 ft/min Qs = 0 Btu/hr M = 125 lbm cy = 0.3 Btu/lbm F p', cp' = look up at appropriate temperature b) Repeat the above for four occupants. Note: Label and plot both curves on one graph. UoAo 50 Btu/hr F = V' = 250 ft
