    Accurately calculating the pressure drop through an orifice

    I have a scenario where a specific nozzle is defined to have a flow of 900cc/min. The flow co-efficient for this nozle is defined @9.8 MPa -> flow co-efficient= 0.85. If I then run fluid through this nozzle at say 200 MPa and I would like to calculate the pressure drop. My understanding is taht...

    Diesel injector sac pressure calculation

    I am trying to calculate the nozzle sac pressure required to deliver 60mm3/ms of diesel fuel into a pressurised cylinder (19MPa). The nozzle has 5 delivery holes of diameter 0.157mm and the discharge co-efficient is 0.87. The sac diameter= 0.7 mm and the sac volume= 0.12mm3. I have tried to use...
