Question
A 3-m * 4-m 3 *-m room is to be heated by one ton
(1000 kg) of liquid water contained in a tank that is placed in the room. The room is losing heat to the outside at an average
rate of 6000 kJ/h. The room is initially at 20°C and 100 kPa and
is maintained at an average temperature of 20°C at all times. If
the hot water is to meet the heating requirements of this room
for a 24-h period, determine the minimum temperature of the
water when it is first brought into the room. Assume constant
specific heats for both air and water at room temperature.
