Chapter 27, Problem 34SP

A tank containing 200 kg of water was used as a constant-temperature bath. How long would it take to heat the bath from 20 °C to 25 °C with a 250-W immersion heater? Neglect the heat capacity of the tank frame and any heat losses to the air.

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 8,2 A from the mains. Assume that the thermal resistance of the tank is Rt=0.04 ℃/W. The temperature of the tap water is 10℃. Maximum temperature of the water in the tank in the steady state is …. ?
An electric immersion heater has a power rating of 1800 W. If the heater is placed in a 1.3 kg of water at 30 °C, how many minutes will it take to bring the water to a boiling temperature? (Assume that there is no heat loss except to the water itself. water=4186 J/kg.°C)
Water flows through a shower head steadily at a rate of 10 L/min. An electric resistance heater placed in the water pipe heats the water from 16 to 43°C. Taking the density of water to be 1 kg/L, determine the electric power input to the heater, in kW. In an effort to conserve energy, it is proposed to pass the drained warm water at a temperature of 39°C through a heat exchanger to preheat the incoming cold water. If the heat exchanger has an effectiveness of 0.50 (i.e., it recovers only half of the energy that can possibly be transferred from the drained water to incoming cold water), determine the electric power input required in this case. If the price of the electric energy is 11.5 ¢/kWh, determine how much money is saved during a 10-min shower as a result of installing this heat exchanger.
