    Cooling Effect of Spa Jets

    Hi All,

    This goes out to the math nerds.

    Could you help with calculating the heat loss from running spa jets. Averages are fine, i.e., flow, nozzle size, nozzle number, water temp, air temp, etc.)

    Thanks a bunch!

    Welcome soaker... I'm sure someone will help you. Me? I hate math! I'll sit in the back of the class for this one!!!

    Welcome to TFP!

    That's not an easy calculation. It would be far easier for you to just measure the temperature drop per time when the jets are running. The temperature drop might be proportional to the temperature difference between the air and the water so you could calculate for other conditions accordingly.
