Problem 1: 7.5 kg of water (c = 4190 J/(kg⋅K)) is heated from T1 = 15° C to T2 = 22° C.

To the heated water 0.5 kg of water at T3 = 20° C is added. What is the final temperature of the water, in kelvin?

    P11-104. Cold water (Cp = 4180 J/kg-K) leading to a shower enters a thin-walled double-pipe counterflow heat exchanger at 15°C at a rate of 0.25 kg/s and is heated to 45°C by hot water (cp=4190 J/kg K) that enters at 100°C at a rate of 3 kg/s. If the overall heat transfer coefficient is 950 W/m2.K, determine the rate of heat transfer and the heat surface area of the heat exchanger using the effectiveness-NTU method.
