Vena Contracta
Vena Contracta
(OP)
When a gas flows from a plenum into a pipe of diameter D, I understand that the vena contracta forms approximately 0.5D downstream from the pipe entrance. How far downstream from the vena contracta or the pipe entrance does the gas flow become fully distributed across the pipe area?
