Rise in room temperature over a one hour period

  1. Feb 26, 2014 #1
    I have a room with no cooling.

    Room info : w = 5m l = 4m h= 2.5m
    Heat dissipation from equipment in room= 65kw
    Ambient temp = 20 degrees celcius

    I need to know the temperature rise over a one hour period

    Please help

    If the room is perfectly insulated and held at a constant pressure (not perfectly sealed), I get a back of the envelope answer that it will rise in temperature by about 3600C in an hour. Obviously, this isn't correct, but this demonstrates that the room will rapidly rise in temperature (~1 degree C per second) until the heatflow out through the walls and whatever venting system exists is equal to the heatflow in.
