Pressure loss steam through contraction
We are in Europe and because of regulations we use the EN-4126. I have no doubts my PRV calculaton is ok. Case is 1058 kg/h saturated steam, set pressure 4 barg, relieve pressure 5,14 bara, gives a orifice of 22,7 mm (4,06 cm2). This PRV selected is certified for 1775 kg/h massflow and for this...- Martin56
