Why is human heart not a centrifuge pump

    1. The problem statement, all variables and given/known data

    Why is human heart not a centrifuge pump but positive displacement pump ?

    2. Relevant equations



    3. The attempt at a solution

    Maybe bcoz there is no continuous flow of blood. blood goes thru body in packets hence we hear heart beats..

    Re: Pumps

    I thing you are getting it reversed - there is no continuous flow of blood because the heart is a displacement pump. Besides, what you wrote is a kind of not-an-answer - it doesn't address "why", just mentions some tangential facts.

    As far as I remember there is only one animal with a strictly rotating organ, apparently these are hard to evolve.
