Line Pressure Drop
Line Pressure Drop
(OP)
Just wanted to confirm if a simple ratio ( old delta p / new delta p ) can be used to prorate the pressure drop in a line for a new flowrate.
new dp = ( Q2 / Q1 ) * old dp.
Thanks
new dp = ( Q2 / Q1 ) * old dp.
Thanks





RE: Line Pressure Drop
Most hydraulics and water piping is turbulent, and pressure drop is very roughly flow squared. i.e. 2 x flow = (2)^2 = 4 times pressure drop. 3xflow = 9x pressure drop.
