    Pipe size and diameter connecting hydraulic pistons

    Hi everyone, In the attached diagram there are two hydraulic systems. The cylinder areas for each system are the same. The only thing that is different between the two systems is the pipe joining them, system B having a much smaller ID. Pascals law states that these two systems would act...

    Converting from Static to Dynamic Understanding the Darcy Weisbach

    Trying to get my head around something with the Darcy Weisbach. It is used to calculate the head loss of a moving fluid within a pipe. So for example if we take a pipe with an entry point 6m above a datum plane and an exit point 1m above the same datum plane. The pipe length is very long, say...

    Pipe Flow: Neglecting Pipe Length

    In the diagram attached I have a pipe (standard concrete) that is going from point A (Entrance) to point B (Exit). Standard water is the fluid within the pipe. Point A (entrance) has a constant uninterrupted supply of water at a velocity of 0.7m/s, how do I find the correct velocity at point B...

    Pascal's Law - Weight of Water Involvement

    Pascal’s Law states “pressure exerted anywhere in a confined incompressible fluid is transmitted equally in all directions throughout the fluid such that the pressure ratio (initial difference) remains the same”. My question is, are the two scenarios that I have outlined the same? (see...
