Now that the team has the pump’s suction pressure in psia. they can easily calculate npsha: To convert from absolute pressure to pressure gauge. subtract the atmospheric pressure:

#### Absolute Pressure Is The Entire Or Total Pressure.

For example. if your tire gauge reads 34 psi (pounds per square inch). then the absolute pressure is 34 psi plus. In practice. a perfect vacuum is impossible to obtain. It is a more technically correct value. but not useful to the industry since the ambient air is never a perfect vacuum.

#### Now That The Team Has The Pump’s Suction Pressure In Psia. They Can Easily Calculate Npsha:

Pabs = pg + patm. Concept of absolute pressure. gauge pressure. and negative pressure. pressure unit conversion. Convert pressure to different units;

#### In Engineering. The Vertical And Uniform Force Acting On The Unit Area Is Called Pressure. And The Difference Between The Two Measured Pressures Is Called Pressure Difference Or Pressure Difference. And Engineering Is Called Differential Pressure.

For recreational and technical divers. bar and atm are said to be equal. whereas ata accounts for the atmospheric pressure pushing down on the waters surface. Pounds per square inch absolute (psia) is used to make it clear that the pressure is relative to a vacuum rather than the ambient atmospheric pressure. The procedure to use the absolute pressure calculator is as follows:

#### Therefore. Absolute Pressure Data Would Need To Be Converted Using Barometric Data. As The Pressure In The Surrounding Atmosphere Changes With Time.

To convert a value from gauge pressure (pg) to absolute pressure (pas). simply add the atmospheric pressure: Pat is the atmospheric pressure; Gauge pressure is the pressure inside a system.

#### Thus A Tire Inflated To A Gauge Pressure Of 32 Psi. Or A Psig Of 32. Would Have An Absolute Pressure. Relative To A Vacuum. Of About 32 + 14.7 = 46.7 Psi. Or A Psia Of 46.7.

Thus a reading of 30 psig on a tire gauge represents an absolute pressure of 44.7 psi. Where p a b s is absolute pressure. p g is gauge pressure. and p a t m is atmospheric pressure. Gauge pressure is a measurement that ignores the atmospheric pressure.
