**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.
