Heat a room of 4 m X 5 m X 7 m with a radiator of a steam
heater.
Heat of 10,000 kJ/h is transferred from the steam heating system,
and a 150 W blower is used to allow warm air to circulate well
indoors. The rate of heat loss from the room is 5,000 kJ/h. If the
temperature of indoor air is initially 15°C, how long does it take
to raise the temperature of the air to 25°C?
(However, it is assumed that the specific heat is constant at the
indoor temperature)
Which one should I use? or
