【Abstract】 This paper puts forward a new testing system for measuring the discharge coefficients of high pressure nozzles. The system can be used to measure discharge coefficient of different nozzles with high pressure spray under different air back pressures. Some experiment results are presented, which prove that the system is much practical.更多还原
