Hi.
I read in "Piping and Engineering" by George Antaki the following example:
Can anybody explain how the trapped air pressure can rise above the hydraulic pressure?
Thanks?
Hi.
Does anyone know what the definitions of AC (Accuracy Class) and SG (lock-up pressure class) are with regards to pressure regulators and slam shut valves?
Thanks!
Hi guys.
Hope someone can help on the following issue.
Our client wishes to backup the NG with SNG (LPG and Air) that supplied to a mono-fuel burner.
I calculated the Wobbe Index of the NG and of the LPG and determined the correct LPG-Air ratio required to attain an identical Wobbe Index of...
Hi there.
Does anyone know if the flow of natural gas to a steam boiler should be determined by the boiler's capacity or rather by it's burner's capacity which is usually substantially bigger? Will the burner not operate at a higher capacity than that of the boiler in order to overcome losses...
Hi,
Does anyone know whether the hybrid pressure method for gas pipe sizing as described in ANSI Z223.1-127, can be used for pressures above 2 psi upstream of the regulators?
Thanks a million.
Hi,
I am trying to calculate the net heat transfer between an open pool filled with water and the atmosphere. Have taken into account radiation, evaporation.
Having difficulties calculation the conduction from the water to the ground and from the water to the atmosphere. The water is warmer...
