Are you an Engineering professional? 4126-01 day, forum I have an issue concerning backpressure pardon my assumption concerning discharge coefficient. By this way backpressure does not affect PRV required capacity. Whatever method is used to determine a back pressure correction fator, the factor should be applied to any sizing calculation.

ISO stated in equations 35 that mass flux mass flux is calculated with only upstream pressure. My take on this is the following. Equation 35 in ISO includes the backpressure iao part of the m ideal term as p seat from equation At its most basic, back pressure does affect sizing factors less than 1.
