    Orifice Sizing Equations

    Hi all, Can someone guide me to a reliable technical resource that has equations for calculating temporary pressure loss, permanent pressure loss, max velocity across an orifice? I’ve seen some equations in the past that take into account orifice details such as thickness, sharp edge etc but...

    Gas Injection Into Liquid Line

    If a higher pressure gas in introduced into one side of a pressurized pipe, would gas bubble through the liquid or displace the liquid? Assume the gas is at higher pressure than the liquid in the pipe and pipe is closed on the other end. Thanks

    Tank Recycle Hydraulics

    I have an interesting hypothetical hydraulics problem in order to better my understanding. Please refer to the attached diagram for clarity. Imagine a closed tank with a roof (not open to atmosphere). It has one inlet, one outlet, one recycle. Inlet line to the tank is through a centrifugal...

    Hydraulic Grade Line Analysis

    Hi, I am looking to figure out where will the flow in the pipeline go from full pipe to slack flow in the attached image? Background: The attached image shows a tailings pipeline going down into a tailings pond. The end of the pipeline is at atmospheric pressure. Since the end point of the...

    Slack Flow Versus Siphon

    Hello, First time posting here, apologies if question is unclear. I have spent hours searching the difference between operating in a slack flow vs in a siphon. Numerous sources say that when Hydraulic grade line (HGL) falls below the pipeline elevation, slack flow occurs. My question is...
