Is it still choked flow if the discharge of the hose is 15 psig instead of atmospheric? The rubber hose I am referring two is a standard utility/industrial hose that is utilized for air, nitrogen, process water within the chemical industry. 3/4" id. Thank you.
I wanted to calculate both the max flow going to atmosphere, and also with an outlet pressure of 15 psig. (75 psi differential). I was going to probably assume 3 or 4 90 degree bends as a minimum, and the rest of the hose straight. I am trying to determine what relief capacity would be...
I am trying to determine the flowrate of nitrogen (90 psig) through a flexible rubber utility hose. I found some online calculators, but want to do some hand calculations to validate. I guess I am looking for friction factor for 3/4" id rubber hose and any other tips. The hose lengths would...
