Cant find an appropriate fluids equation

  1. Apr 5, 2006 #1
    Hi guys this is my first post on here, and I like the look of it so far. I've tried to look everywhere for an approprate equation for this question but I cant come up with one, or maybe Im overlooking something.

    What is the minimum power (W) required to pump blood in the human body? Assume a total average pressure rise across the heart of 120 mm Hg.
    Given: 80 beats per minute, stroke volume of 70ml, volumetric output is 336 liters per hour.

    Thanks,
    Ben

    Thank you very much for that link it was very helpful. I didn't expect a straight out answer, I was just quoting the problem exactly.

    I got 1.49 watts, which sounds about right.


    Thanks,
    Ben
