Based on the service and requirements, RO should be sized for critical or pre-critical condition. Generally, pressure control RO plates are sized by considering the maximum pressure drop lesser than the critical pressure. dagnachew \u0026 mahlet law office dmlo

"WitrynaFor practical computations, one important parameter of the orifice problem is the ratio of the width of the jet to the width of the orifice opening. This ratio is called the contraction coefficient, and it is needed to compute the jet width at the vena contracta, where the pressure is uniform across the jet. " - Importance of orifice
