    Oil pressure guru's, fluid dynamics help needed!

    Thanks TDk2, You've described everything right on. The one thing that confuses me is the pressure remained the same no matter which line I used. The pressure gauge is located inline of the lines between the pump and the input of the block. What confuses me is I know the larger lines can flow...

    Oil pressure guru's, fluid dynamics help needed!

    Thanks Pumpdesigner, Hope you can answer what I hope is the last simple question. If the smaller line wasn't up to the flow rate in this system what would you see happen to the pressure? Thanks Randy

    Theoretical flow rate?

    Forgot to add maximum pressure for the input line has already been tested at 60lbs. Randy

    Theoretical flow rate?

    Need help in getting a rough idea for the maximum potential flow two openings will permit. The diameter of the two orifices are 0.078" and 0.219". Fluid is motor oil 20W-50. Orifices are fed off the same input line that has a diameter of 0.25". I'm guessing this supply line will...

    Oil pressure guru's, fluid dynamics help needed!

    Thanks for the insightful reply pumpdesigner. Maybe you can help with one more question regarding the same concern. I tested the output of the pump at idle (950rpm) using the 5/32 line and the 3/8 line. Both lines delivered roughly .72 gal/min. If I remember correctly the 5/32 line was...

    Oil pressure guru's, fluid dynamics help needed!

    Hi everyone, I;ve been trying to find an answer to my question below in vain. Found this forum and hope someone here can give some professional insight. I have an engine with a constant volume oil pump, that feeds the oil to the motor using 1/4" oil line. With this 1/4" oil line it...
