6. A 50-liter hot-water tank is used in the laundry service of a hospital clinic. The water in the tank is heated up using an electrical heater that is operated from 200V (mains) power line. The heater draws 5 A from the mains. Assume that the thermal resistance of the tank is Rt=0.04 °C/W. The temperature of the tap water is 10°C. How much is the maximum temperature of the water in the tank in the steady state?
