Heat problem

  1. Feb 18, 2004 #1
    I thought I was doing this problem right but I was told I wasn't. Can anyone help me pinpoint my problem?

    A refrigerator has a surface area of 7.09 m^2. It is lined with 0.0918-m-thick insulation whose thermal conductivity is 0.0300 J/(s m C°). The interior temperature is kept at 5.88 °C, while the temperature at the outside surface is 21.7 °C. How much heat per second is being removed from the unit?

    Here's what I did:
    Q/t=AK delta T/L
    =(7.09)(.0300)(15.82)/.0918 = 36.7

    Looks right to me.
