1) You a re tasked with designing an orifice meter to control the flowrate of fluids. Design Conditions You are required to do the following: a) Estimate the co-efficient of discharge and justify your reason. b) Design single orifice plate with D and D/2 pressure taps and vary the inlet pressure to achieve to get required mass flowrate at the following conditions: a) Sub-sonic flow b) Choked flow Note: Orifice plate should be same at both flow conditions and for all 3 flow medium
