Effect of changing nozzle shape from circular to oval on discharge coefficient and mass flow rate

Effect of changing nozzle shape from circular to oval on discharge coefficient and mass flow rate

By changing the shape of nozzle to oval in two steps, it has been observed that only a little change in the value of mass flow rate occurs. That is, mass flow rate changes from 0.14 kg/s in M tool nozzle to 0.13 and 0.132 in oval shaped nozzle 1 and 2 respectively
