Q2/ Consider a 1.2-m-high and 2-m-wide glass window whose thickness is 6 mm and thermal conductivity is k = 0.78 W/m. °C. Determine the steady rate of heat transfer through this glass window and the temperature of its inner surface for a day during which the room is maintained at 24°C while the temperature of the outdoors is 5°C. Take the convection heat transfer coefficients on the inner and outer surfaces of the window to be h1 = 10 W/m2 °C and h2= 25 W/m2 °C, and disregard any heat transfer by radiation.

A computer room located on the second floor of a five-story office building is 10m by 7 m. The exterior wall is 3.5 m high and 10 m long; it is a metal curtain wall (steel backed with 10 mm of insulating board), 75 mm of glass-fiber insulation, and 16 mm of gypsum board. Single-glazed windows make up 30 percent of the exterior wall. The computer and lights in the room operate 24 h/d and have a combined heat release to the space of 2 kw. The indoor temperature is 20 C. (a) If the building is located in Columbus, Ohio, determine the heating load at winter design conditions. (b) What would be the load if the windows were double-glazed?

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 I bar.
