High Pressure Valve Manufacturers. Many years ago EPRI did a study on why large diameter butterfly valves were cavitating in large supercritical power plant even though the equations indicated they shouldn't be cavitating. In order to specify a control valve a program such as AFTs Fathom can be used.
Still, most of them will allow you to do some decent process evaluations, etc.
But not all engineering companies use PDM equally. Many programs require inlet and outlet pressures to be input in absolute pressure units. This is very helpful in optimizing loop tuning. If so please provide details. A cylindrical mechanism in a brass instrument that, when depressed or turned, admits air into different sections of tubing and so extends the range of tlowserve notes.

You are probably not going to get much more than you could calculate by using standard engineering references like Perry's, Marks, Crane, Cameron Hydraulic, et. Valve sizing programs Both Fisher and Valtec has good software that should be avaiable for free from the vendor. Download Now 3D printing is developing fast.
On the other hand, if you mean a "valve sizing program" to determine what the required Cv of the valve would need to be, then that is a different type of program. They found that the equation was based on the flow to square root of delta P curve of a globe valve. Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden.
Valve sizing programs Can you give more info, what kind of valves?

To be honest nothing else really comes to mind on how to describe what appeared to be a rock that was approximately the size of a house.

When and if i ever get the job for describing objects and inscribing those descriptions on a sign to be placed below fixed telescopes I can only hope to do a little better then "house sized rock".
Dot be tempted to save a few bob and leave all to the salesmen. However, like others the Fisher software can be downloaded over the web.
