I made a jet/venturi pump from a 2" T ,1" discharge and 1/2" air inlet through a 1/8 nozzle,air at 120psi. Suction is 2" pipe about 5' long. Problem is that I'm only getting about 3gpm. Would decreasi

I agree with your sentiments and I still do not really know why 9.6.1 was withdrawn.My problem is that I am investigating the case of a 3x350MW coal fired sub-critical plant where the EPC contract say

High speed shaft coupling I am in the process of designing a hydrostatic thrust bearing test stand for a small hydraulic turbine. The turbine's shaft will be driven with a VFD controlled spindle motor

I am working on making improvements to an existing water system and have a few questions. Background: 66 homes spread over 6 miles; distribution pipes are 4", 2", and 1.5"; Currently the well's 10 hp

The design is reasonable, and I agree that the expected pressure drop would be well below what you are experiencing. Assuming that your over-reading pressure gauge is accurate and you do have >22 psi,

The pump, being a positive displacement gear pump, will pretty much reach any pressure required to move your fluid UP TO THE POINT that either it runs out of the power required to do so, breaks down,

The pump seems to be a pressure and flow compensated hydraulic piston pump. That means at a certain pressure the swash plate moves and changed its angle. By doing this the stroke of the pistons is red

My thinking on the coupling failure is that overheating in the pump could cause axial force imbalance within the pump envelope and axial shifting of the pump shaft greater than the coupling can handle
