Experiment question- energy consumed from single shower

  1. Oct 3, 2013 #1
    1. The problem statement, all variables and given/known data
    Not really a problem but more of an experiment.
    Attempting to measure the amount of energy used for one typical shower
    I have come up with these units, I need help figuring out the energy being consumed through the shower water use and shower water cost. Some equations would be very helpful.

    Average Shower Time: 17 Minutes
    Shower Head Water Usage: 2.5 gallons (U.S. Average) per minute
    Water Cost: $2.00 per 1,000 gallons (U.S. annual average for price)
    Water Heater Usage energy type: Electric
    Cost of Water Heater Usage: $0.17 per kWh
    Water Temperature: Calculated at approximately 61 degrees Fahrenheit
    Shower Temperature: Calculated at approximately 115 degrees Fahrenheit



    2. Relevant equations
    the issue is I am not sure what equation needs to be used to solve for energy


    3. The attempt at a solution
    Dont have an attempt without the equations
    1. The problem statement, all variables and given/known data



    2. Relevant equations

    Q = mcΔT

    You know the mass, you can look up the specific heat capacity and you can calculate by how much you want to heat the water by.
