In order not to damage the resistance in the kettles, the difference between the temperature ofthe heater and the fluid should not exceed 25 oC. If the heat transfer area between the fluid andthe heater is 78.5 cm2 and the heat transfer coefficient is 400 W/m2.K, find the maximumallowable power of the heater in order to boil water?
A 3 ohm heater takes 6 amperes while submerged in 1200 grams of water contained in a vessel with a water equivalent to 200 grams. What is the efficiency of the system if the time required for the temperature to change by 70 degrees Celsius is 3.95 hours?
A small electric immersion heater is used to heat 100 g of water for a cup of instant coffee. The heater is labeled “200 watts”. Calculate the time required to bring all this water from 23.0 °C to 100 °C, ignoring any heat losses. Assume specific heat of water is 4.187 J/g-°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.
