Force on a Fluid in a Control Volume Calculator

Force on the fluid (F):

Flow rate (Q):

Density of fluid (ρ):

Velocity 1 (v₁):

Velocity 2 (v₂):

How This Is Calculated

$$F = Q \rho (v_2 - v_1)$$
where:

F = Force on the fluid (N)

Q = Flow rate (m³/s)

ρ = Density of fluid (kg/m³)

v₁ = Velocity 1 (m/s²)

v₂ = Velocity 2 (m/s²)

Assumptions

Flow is two dimensional and frictionless.
The fluid is in steady flow.
The fluid is incompressible.
Body force forces are neglected.
