Homework Help: Geothermal energy, aquifer

  1. Apr 18, 2014 #1
    1. The problem statement, all variables and given/known data

    See attachment

    2. Relevant equations

    I guess I need to do something with this equation:
    P= cmρJΔT

    ρ is then the density of water 1000m3/kg
    J is given
    Cm is given
    But what to do with the temperatures... ΔT= Th-Ta? But then you get a negative number and the ask for the power delivered...

    Sounds like you have the right idea. The energy the water loses equates to that energy going to heating the house.

    Don't forget that power = rate of delivering energy
