A bit on the high side but my plumber says it s fine My expansion tank is set to about 15 lbs less than the house because of the irrigation system It lowers the pressure so much that if the expansion tank is set to the house pressure it introduces air into the house plumbing I m not sure how the physics works out I just know it does

Distribution Piping Understanding Pressure Drop

The compressor room header into which the air compressor s discharge s should be sized so that the air velocity within the header does not exceed 20 ft/sec allowing for future expansion Distribution header piping leaving the compressor room should be sized to allow an air velocity not to exceed 30 ft/sec to minimize pressure drop

Distribution Piping Understanding Pressure Drop

The distribution piping system often is diagnosed as having excess pressure drop because a point of use pressure regulator cannot sustain the required downstream pressure If such a regulator is set at 85 psig and the regulator and/or the upstream filter has a pressure drop of 20 psi the system upstream of the filter and regulator would have to maintain at least 105 psig

Speed of sound in air temperature barometric pressure

The humidity of air has some negligible effect on the speed of sound The air pressure and the density of air air density are proportional to each other at the same temperature It applies always p ρ = constant rho is the density ρ and p is the sound pressure Therefore air pressure does not enter the calculation of the speed of sound of air

Pressure Testing with Air Versus Pressure Testing with

To find leaks a low pressure 30 50 PSI air test is just as effective as high pressure 150 PSI water test This is because the viscosity and surface tension of water is greater than that of air For example the viscosity of water is about 89 times greater than the viscosity of air

Testing water pipes with air Physics Forums

1 041 4 Pressure testing with water is fairly safe unless you re very close to the leak Water is only slightly compressed at a pressure of 8 bar and loses it s energy quite quickly as it expands Air is a different story since it is greatly compressed at 8 bar the rupture of a pipe can send shrapnel flying

Copper Unit of Pressure CUP Defined by Hodgdon

A Copper Unit of Pressure CUP is a measurement used in the ammunition industry to determine the chamber pressure created by a cartridge load Originally a precisely formed copper slug was placed in a fixture over the chamber When the cartridge was fired the amount of crushing measured on the slug allowed engineers to determine the pressure

Air Density CalculatorWhat is the Density of Air

For dry air its density at sea level at 59 F 15 C and 14 7 psi 1013 25 hPa mean sea level pressure is approximately 0 0765 lb/cu ft 1 225 kg/m³ If you change the air temperature humidity or the altitude and hence the pressure the air density will change too
