Cold water (cp = 4.18 kj/kg·k) enters a crossflow heat exchanger at 14°c at a rate of 0.35 kg/s where it is heated by hot air (cp = 1.0 kj/kg·k) that enters the heat exchanger at 65°c at a rate of 0.8 kg/s and leaves at 25°c. determine the maximum outlet temperature of the cold water and the effectiveness of this heat exchanger.

In a good thermo flask the main cause of heat loss is
