Convert 40 Inches Water to PSI - Thermodynamics Help

[wub1098]

A manometer measuresa pressure difference as 40 inches of water. What is this pressure difference in psi?


solution with short ecplanation would be very appreciated thanks

To convert inches of water to psi, we first need to understand the units of measurement. Inches of water is a unit of pressure, specifically a unit of pressure difference. It is commonly used in measuring small pressure differences, such as those found in manometers.

On the other hand, psi (pounds per square inch) is a unit of pressure commonly used in thermodynamics. It is also a unit of pressure difference, but it is typically used to measure larger pressure differences.

To convert from inches of water to psi, we can use the following formula:

1 psi = 27.68 inches of water

Therefore, to convert 40 inches of water to psi, we can multiply 40 by 27.68, which gives us 1,107.2 psi.

In summary, the pressure difference of 40 inches of water is equivalent to 1,107.2 psi. This conversion is important in understanding and comparing pressure measurements in different units.
