Does anyone have a "rule of thumb" to determine under what general conditions to use metallic gaskets and alloy studs?

bluemax; I would rather attempt to design a perpetual motion machine rather than try to apply Maxwell's equation to this problem. I have recently reviewed a printout of a proposed steam turbine that was prepared using "steam master 5.30" software. Gland steam losses are shown on the...

One thing that has not been mentioned with a VFD; if for some reason the pump will be required to pump significantly less flow (i.e. slow RPM) the motor could overheat and burn out due to insufficient cooling from its fan. Special precautions may be required in motor selection.

What is the maximum recommended horizontal spacing between pipe supports for 30" standard weight steel pipe? I am looking at Anvil International catalogue PH 2002, page PH 207 which states 34ft. Unless I misunderstand piping design, I feel that the 34 ft is a "typo".

The mechanical energy does not match the electrical energy due to inefficiencies in the steam turbine, the electrical generator and gearbox(if utilized). Mechanical energy is developed through the turbine by virtue of high pressure steam passing through turbine blading to a lower pressure. The...

There are regulations with regard to pipeline isolation. Depending where (state, province, country, etc)the system is located, the regulations vary. Usually worker safety boards predicate the regulations. I would contact the juridiction that regulates worker safety. My gut feel is that the...

Has anyone ran across a good book that states, or have a proven "rule of thumb" for estimating the average gland and labyrinth seal losses through an extraction/backpressure steam turbine. I want to use this number in calculating the net shaft power developed by the turbine. The...
