    How to translate from vertical motion to rotational

    Imagine, if you will... A valve which is typically actuated via vertical displacement (downward stroke)... However, I have managed a means to activate the valve via rotational motion. I was hoping to get a few ideas from the forum on how to translate the vertical motion (I have to deal with...

    Annular flow for a given area

    How does one compute the annular flow rate given the area? Assume 35 psi and water (@ room temp) as the fluid. Example: I have a piston within a cyclinder. The annular area between the piston and the cylinder is .091 in^2. Pressure is 35 psi. For ease of calculation consider this a static...

    Venturi Optimization

    How can a venturi for air induction be optimized? I am inducing air into a closed vessel via water flowing circumferentially about a tube vented to atmosphere. The nature of the water flow creates a negative pressure (vacuum) and induces air into the closed volume (there is a one-way check valve...
