Fluid Dynamics

  1. Feb 15, 2014 #1
    1. The problem statement, all variables and given/known data

    Imagine this submersible well pump pumping water straight up

    volume flow 1 liter/second
    fluid speed 10m/s

    Since pump is pushing on the fluid, fluid has to push on pump as well

    Will it be linear vector force downward or torque or combination of both ?

    How do i calculate their magnitude?

    2. Relevant equations

    m1 u1 + m2 u2 = m1 v1 + m2 v2

    Also Δp1 = −Δp2

    3. The attempt at a solution

    I assume combination of both reaction forces.

    Looking at the picture, the pump seems to eject water vertically, from the head located on its vertical axis of symmetry. So I think there is no torque to speak of.
