Please help me on this .

- An insulated, electrically heated tank for hot water contains 240 kg of liquid water at 85C when a power outage occurs. If water is withdrawn from the tank at a steady rate = 0.2 kg/s. Assume cold water enters the tank at 15C and negligible heat losses from the tank. For liquid water let Cv=Cp=C, independent of T and P. The time in seconds to take the temperature of the water in the tank to drop from 85 to 60C is O 151.4855 128.8265 111.6316 414.4588
