(Q1) A 5m x 8m × 4m room contains air at 97 kPa and 8°C. The room has a 380 W refrigerator, a 200 W television, a 2.1 kW electric resistance heater, and a 130 W fan. During a cold winter day, it is observed that the refrigerator, the TV, the fan, and the electric resistance heater are running continuously, and the air temperature increased to 19°C within 24 minutes. If the pressure always remains the same, determine the rate of heat loss from the room during that day in

Question

do not approximate the numbers you get from the tables write it as it

(Q1) A 5m x 8m x 4m room contains air at 97 kPa and 8°C. The room
has a 380 W refrigerator, a 200 W television, a 2.1 kW electric
resistance heater, and a 130 W fan. During a cold winter day, it is
observed that the refrigerator, the TV, the fan, and the electric
resistance heater are running continuously, and the air temperature
increased to 19°C within 24 minutes. If the pressure always remains the
same, determine the rate of heat loss from the room during that day in
kJ/h.
