Answer Posted / carl_ellis
Theoretical burst and working pressure in psi at 100 degrees F
Pressure Formula:
Internal Burst = 2 St/D
Where
P = Internal pressure psi
S = Tensile stress psi
t = Minimum wall thickness in inches
D = Nominal outside diameter in inches
Working pressure = 1/4 internal burst pressure

Calculate the maximum pressure drop that can be allowed to occur across a control valve, so that we can prevent cavitation / flashing from occurring. Use the following formula: Δ P allow = Km (P1 – PvapourA) where, Δ P allow - the maximum allowable differential pressure for sizing purposes, or terminal pressure drop; Km- the valve recovery coefficient from the manufacturer’s catalogue; P1 - absolute inlet fluid pressure; PvapourA - absolute fluid vapour pressure at the inlet temperature; Use Atmospheric pressure = 101.3 kPa, P1 = 1200 kPa(g), PvapourA = 4 kPa, KM = 0.72
