I am looking for a differential pressure regulator. I have one source, or pipe, which is P1 at say 250 lbs constantly. Then P1 will supply P2 with a pressure increase if necessary. The pressure will move into P2 according to the regulator to give the desired pressure for P1. P2 and P1 are...

The suction line is 8 inch. Yeah I would imagine the same thing with the catalyst heal and how that would screw up the pump.

Main Column Bottoms of the the FCC so it is sort of a mixture of asphalt similar substances. I do not believe that there are and Chloro benzenes.

The problem starts with a MCB process. The pumps are internal rotary gear, and pump from a 30 foot high tank. They are about 20 feet from the tank, the centerline of the pumps no higher or lower than the outlet from the tank. Some of the givens, Temp-240 Deg. Product Visc.- 450 cST Spec...

Howdy all, I am looking into integrating certain software that is currently developed for a pocket PC, and using it on a Tablet PC. Now I know that there has to be software that I would be able to load on the Tablet PC that would act as a Platform to sustain and run the Pocket PC application...

Hey, I have been searching through many of the threads that have arised and have become a bit confused. I understand about the NPSHr on the curve. I am looking into the NPSHa of the curve goign for VGO. I have a tank that is 40 Ft tall. Open up to Atmospheric press. I have all of the Line...

Well I am doing a line loss survey to see why a couple of pumps are cavitating and the NPSHa among many things is a variable of Vapor Pressure as well. I am already on the line of NPSHa not being enough for the NPSHr. One foot in either direction could be good or screw me.

Hey, The Suction energy equation is set for the Centrifugal pumps. But does anyone know the proper way to calculate the suction energy of a pump that has twin screws/gears? The suction energy is actually the liquid momentum in the imperllor but the way that the pump is designed there is no...

Howdy all, I need to find the Vapor Pressure of VGO 100-120 Deg F, Asphalt 300-350 Deg F, and MCB 200 Deg F. I understand about their characteristics I have just hit a wall with the vapor pressure. Would anyone be able to point me in the right direction for a website or source that is...
