Fluid Flow

Calculate the fluid velocity in a pipe

Calculator

Governing Equation

This calculator finds the velocity of fluid in a pipe. This is useful for more advanced calculations like determining the Reynolds number and pressure drop through a system. The governing equation is a function of flow rate and pipe geometery

v=Q/Aiv = Q/A_{i}

The following equations are used to find the pipe geometery:

di=d0−2xwd_{i} = d_{0} - 2x_{w}
ri=di/2r_{i} = d_{i}/2
Ai=πri2A_{i} = \pi{r_{i}^{2}}
