Answer to Question #13302 in Other Engineering for omar
A stadium has internal dimensions of 11 m x 4 m x 3 m high. The doors in this construction occupy 6m2 and 20% of the wall area is glazed. The inside air temperature is maintained at 18°C when the outside air temperature is -2°C. There are 4 air changes per hour. Total heat gain for the building is 2200W. The U-values in W/m.K are: walls 1.6, windows 5.5, doors 2.5, roof 1.5 and floor 0.8. The volumetric specific heat capacity of the air is 1300 J/m3K. The output of the radiators is 440 W/m2 of radiating surface.
a) Calculate the net rate of heat loss from this building. b) Calculate the surface area of the radiators required to maintain the internal temperature under the above conditions.
