If i measure pressure at inlet pipe by gauge as say 200psig ( absolute pressure = 200+14.7 = 214.7 psia )
So in my flow simulation should i consider static pressure = 214.7 psi or Total pressure = 214.7 psi ?
Also please explain the reason .
If you measured 200PSIg as the static pressure, then use that in your simulation. You didn't measure the absolute pressure, so you don't know what it is.
Total pressure = static pressure + dynamic pressure. If you input 214.7PSI as your total pressure, you will lose mechanical potential energy, as your total pressure is in fact much higher, assuming your fluid isn't stagnant.
I believe it should be Static Pressure. As absolute pressure is the absolute static pressure
