Inches Of Water Column To Psi Conversion Chart
When it comes to measuring pressure, there are different units of measurement that are used. One of the commonly used units of measurement is pounds per square inch (psi). Another unit of measurement is inches of water column (in. w.c.). It is important to understand how to convert from inches of water column to psi, especially in situations where both units are used.
Understanding Inches of Water Column
Inches of water column is a unit of pressure measurement that is commonly used in the HVAC industry. It is used to measure the pressure difference between two points in a system. One inch of water column is the pressure exerted by a one-inch column of water at its maximum density.
This means that if you were to take a U-shaped tube and fill it with water, the pressure difference between the two ends of the tube would be measured in inches of water column.
Understanding Psi
Psi stands for pounds per square inch. It is a unit of pressure measurement that is commonly used in a variety of industries, including automotive, manufacturing, and construction.
Psi measures the force exerted on an area of one square inch. For example, if a force of 100 pounds is applied to an area of one square inch, the pressure would be 100 psi.
Converting Inches of Water Column to Psi
Converting inches of water column to psi is a simple process. The formula for converting inches of water column to psi is:
psi = in. w.c. / 27.7
This formula assumes that the temperature is 68°F (20°C) and the gravity is 9.81 m/s². If the temperature or gravity is different, the conversion factor will also be different.
For example, if you have a pressure reading of 10 inches of water column, you can convert it to psi using the formula:
psi = 10 / 27.7 = 0.36 psi
Using a Conversion Chart
Another way to convert inches of water column to psi is to use a conversion chart. A conversion chart is a table that shows the equivalent values of different units of measurement.
Here is an example of a conversion chart for inches of water column to psi:
When to Use Inches of Water Column or Psi
Both inches of water column and psi are commonly used units of pressure measurement. The choice of which unit to use depends on the application.
Inches of water column is commonly used in the HVAC industry to measure the pressure difference between two points in a system. Psi is commonly used in the automotive, manufacturing, and construction industries to measure the pressure of fluids and gases.
Conclusion
Understanding the relationship between inches of water column and psi is important, especially in situations where both units are used. Converting between the two units is a simple process that can be done using a formula or a conversion chart.
