bcd,
Unfortunately we are the manufacturer. It is my understanding that the torque coefficient (Ct) method is useless unless the Reynolds number of the test case and that of the actual application are similar. Ct differs greatly from Re ~ 10^5 (water flow test case) to Re ~ 10^7 (actual...
I was not clear. I am keeping dynamic pressure constant between the application and test conditions, not constant during the test. This is just to define the initial flow condition. As the blade rotates the flow/pressure is what it is and is not being controlled. I am trying to come up with...
Hello All,
I am writing a test procedure for water flow testing a 10 inch butterfly valve. The application is 10000 GPM liquid hydrogen at 15 psig at the inlet. In addition to pressure drop, I am trying to model the dynamic load (torque) to the blade/shaft assembly experienced at the...
After some extensive web searching, I found both volumes at the following URL's:

They are not the best quality, so if anyone knows...
Does anyone know of a good electronic source for the TRW "Aerospace Fluid Component Designers' Handbook" (volumes I and II, rev D, 1970, preferably) that doesn't cost an arm and a leg? I can only find paper copies at the www.NTIS.gov website.
