Q-2/ An office room has an area of 7*5 square meter and 4m height, this room is heated by the radiator of a steam-heating system. The steam radiator transfers heat at a rate of 10 MJ/h, while a 100-W fan is used to distribute the warm air in the room. During this process, the rate of heat loss from the room is estimated to be about 5 MJ/h. If the initial temperature of the room air is 15°C. Determine; how long it will take for the air temperature to rise to 25°C. Assume constant specific heats at room temperature and the parametric pressure is 1 bar.
