Since, a control scheme that changes displacement is really just changing the clearance (since the cylinder, and piston are fairly rigid), you are decreasing the effeciency (i.e., increasing the ener

Bernard Weisberger: Onward Wisconsin How strange and wondrous it must be to gaze from some celestial perch and see history -- your history -- being relived. From their great Progressive Precinct i

Ansys, FSI, piezoelectric micro-pump example I am using Ansys 12.1 and trying to repeat the Ansys example on MFX (coupled-field analysis guide 4.5, piezoelectric actuated micro-pump). I have followed

An optimum H-Q BEP should be sought at a mid-point of conditions. The duty point will shift back and forth along the curve as conditions change. The NPSHa is usually stable in a Water Treatment Plan

Pump power calculation I have the following situation:3 coolingwaterpumps, 3 different coolingwater users with gascoolers, coolingwaterpressure reading, coolingwaterflowreading.Can I use the formula a

Hey guys and or gals, I had thought of using steam but the air was more easily available. May do it yet if I can talk my boss around to putting in the connections. The original idea came from the PM S

I realize that I may be a bit behind the times, but I thought I would add a little to this thread.NPSHr + 10% or 2-ft, whichever is greater, is the absolute minimum gap between NPSHr and NPSHa when us

NPSH margin and ANSI/HI 9.6.1 I have been asked to investigate what NPSH margin should be applied to power plant boiler feed pumps. I have discovered that ANSI/HI 9.6.1 addressed this particular matt
