Physical properties of fluid and fluid transport in piping system
Laminar and turbulent flow in pipe
Flow mean velocity
Flow in pipes and valves theory - full content
Velocity of fluid in pipe is not uniform across section area. Therefore a mean velocity is used and it is calculated by the
continuity equation for the steady flow as:
Pipe diameter can be calculated when volumetric flow rate and velocity is known as:
where is:
- D - internal pipe diameter
- q - volumetric flow rate
- v - velocity
- A - pipe cross section area
If mass flow rate is known than diameter can be calculated as:
where is:
- D - internal pipe diameter
- w - mass flow rate
- &rho - fluid density
- v - velocity
