Hello Herks Hydra Expertise!
1. It has mentioned Intermediate level maintenance T.O of EDP NYAB at 3000 RPM , flow rate of pump is 6 GPM min, where pump is designed 10 GPM at 3650 RPM . when both the pumps (NYAB) In Aircraft utility system working parallel max flow ie 16.93 pressure drop to 1800 psi. how we can calculate flow rate (GPM) of both NYAB pumps when they are working parallel at 3000 RPM?
2 Just assume that aircraft hydraulic utility system ,when No 1 EDP pressure is 3000 psi and No.2 EDP pump pressure 3100 psi how the pressure act passes thru passage of single pipe after isolation check valves ?
