Expression for pressure drop
Posted: Sun Sep 26, 2010 9:10 pm
I have a simple pressure drop question. I am conducting a simple experiment to measure pressure drop across various pipes and fittings. I am having trouble verifying the expressions that I have found concerning "sudden expansion" and "sudden contractions" fittings. I need an equation that will allow me to calculate the pressure drop through these fittings and maybe a reference. Pipe specs..(1) Brass, 1/2 schedule 40, 15 feet and (2) steel, 1/2 schedule 40. Sudden expansion 1/2 to 1 in. Sudden contraction 1 to 1/2 in. The fluid that is flowing through the pipes is compressed air
