C
According to formula 1, the maximum flow rate
Pressure ratio
Based on Graph (1), it is going to be 0.7 if it is read by the pressure ratio as 0.8 and the flow ratio to be
Hence, flow rate = Max. flow x flow ratio = 600 x 0.7 = 420 [dm
Attach a test equipment with the test circuit shown in Fig. (1) while maintaining the upstream pressure to a certain level which
does not go below 0.3 MPa. Next, measure the maximum flow to be saturated in the first place, then measure this flow rate at
80%, 60%, 40%, 20% and the upstream and downstream pressure. And then, obtain the sonic conductance
maximum flow rate. Besides that, substitute each data of others for the subsonic flow formula to find
