A question of heat

  1. Feb 13, 2004 #1
    Can anybody tell me if there is a way to work out how hot it gets in a glasshouse?
    I realise it would depend on the properties of the glass but I don't know that either. Which properties do what?
    thanks guys

    Find the energy going into the greenhouse -- i.e., from sunlight through the glass roof.

    Find the amount of energy that leaves the greenhouse as a function of temperature -- i.e. from heat rerediated through the glass, and absorbed by the earth, and lost through the walls.

    Solve for the temperature that makes them equal.

    I use THIS software. It does the opposite of what you are asking: it calculates the heat flux for a given set of conditions. It wouldn't be too tough to use trial and error to find the temperature at which the heat flux is zero.
