I thought psia means psi as in absolute pressure? if it is, then I would need to add 1630 kpa( if its gauge pressure) to atmospheric pressure, which would be 246.42 psi+14.7 psi, but the correct answer is just simply 246.42 psia.CWatters said:
A pressure gauge typically gives the pressure in a water line as gauge pressure. So, you are absolutely right in your criticism of question. I would have given the same answer you gave.EastWindBreaks said:
haha, I am not sure if i was criticizing the question or just confused, thank you for clarification!Chestermiller said:
Gauge pressure refers to the pressure measured above atmospheric pressure, while absolute pressure refers to the pressure measured relative to a perfect vacuum. Gauge pressure is typically used for practical purposes, while absolute pressure is used in more precise scientific calculations.
Pressure in a water line is typically reported in units of pounds per square inch (psi). This unit is commonly used in the United States and other countries that use the Imperial system. In countries that use the metric system, pressure may be reported in units of kilopascals (kPa) or bars.
Fluctuations in water line pressure can be caused by a variety of factors, including changes in demand for water, leaks or blockages in the water line, or changes in the elevation of the water source. Changes in pressure can also be a result of faulty pressure regulators or water pumps.
Pressure in a water line is typically measured using a pressure gauge, which is a device that converts pressure into an electrical signal or mechanical movement. The gauge is connected to the water line and displays the pressure in units of psi, kPa, or bars.
Yes, pressure in a water line can be too high, which can lead to damage to pipes, appliances, and fixtures. This is why pressure regulators are often installed in water lines to maintain a safe and consistent pressure. High pressure can also result in water waste and higher utility bills.
