It means pounds per square inch gauge and Is used to measure pressure
0.5 psig is equivalent to 13.8 inches of water column.
50 psig is equivalent to 64.7 psi. To convert psig to psi, you simply add the atmospheric pressure at sea level, which is about 14.7 psi.
Using the ideal gas law equation P1V1 = P2V2, with initial pressure (P1) = 10 psig, initial volume (V1) = 30 ft^3, final volume (V2) = 25 ft^3, we can solve for the final pressure (P2). (10 psig * 30 ft^3) / 25 ft^3 = 12 psig, so the new pressure would be 12 psig.
The condensing temperature for an R22 system with a head pressure of 296 psig would typically be around 120-130°F. This is based on the saturation temperature corresponding to a pressure of 296 psig on the R22 pressure-temperature chart.
The evaporation temperature of R-134a at 0 psig (or atmospheric pressure) is around -26.2°C (or -15.16°F).
psia to psig psig - 15 15 - 15= 0 psig
psia=psig+atmospheric pressure where, atmospheric pressure = 14.7psi therefore psig=psia-atmospheric pressure psig=100-14.7 psig=85.3psig
70 psig
psig
0.5 psig is equivalent to 13.8 inches of water column.
55 psig +15=70
Up to about 150 psig or so. Yes. Graphite is used for shaft seals on steam powered equipment.
50 psig is equivalent to 64.7 psi. To convert psig to psi, you simply add the atmospheric pressure at sea level, which is about 14.7 psi.
To find the pressure at the inlet of the evaporator, you subtract the pressure drop from the low side pressure. Given a low side pressure of 15 psig and a pressure drop of 10 psig, the inlet pressure would be 15 psig - 10 psig = 5 psig. Therefore, the pressure at the inlet of the evaporator is 5 psig.
PSIG refers to pound/force per square inch gauge, while PSI measures the pressure relative to a vacuum. If you want to convert a figure from PSIG to PSI, you would need to add 14.7psi to your PSIG figure, which will give you your PSIA result.
