A current of 14.6 A flows through a 129 Ohm resistance heater. Calculate the heater power in W.
An electric baseboard heater receives 1500 W of electrical power that heats the room air, which loses the same amount out through the walls and windows. Specify exaclty where entropy is generated in that process.
A current of 15.0 A flows through an electric heater operating on 120 V. Compute the power consumption of the electric heater.
Problem 12 Room air at 23°C is heated by a 2000 W space heater with a surface filament temperature of 800 K. The room, at steady state, looses the power to the outside, which is at 7°C. Find the rate(s) of entropy generation and specify where it is made. Set up control volumes around the heater, the space between heater and the room, and the wall between the inside and outside.
