WebVacuum pressure is measured relative to ambient atmospheric pressure. It is referred to as pounds per square inch (vacuum) or PSIV. The electrical output of a vacuum pressure transducer is 0 VDC at 0 PSIV (14.7 PSIA) and full scale output (typically 5 VDC) at full scale vacuum, 14.7 (0 PSIA). The vacuum pressure transducer gives an increased ... WebPressure vs. Head Unit Converter - Pressure vs. head units - like lb/in 2, atm, inches mercury, bars, Pa and more. Pumping Water - Required Horsepower - Horsepower required to pump water. Pumps - Affinity Laws - Turbo machines affinity laws can be used to calculate volume capacity, head or power consumption in centrifugal pumps when changing speed or … WebIn some cases, pressure of gases is measured as the difference between the total or absolute pressure and the atmospheric pressure. This is known as gauge pressure, and it is the pressure measured when determining the air pressure in car tires. Measuring devices often show gauge pressure, although absolute pressure sensors are also in use. aczino musica
