cfh to psi Calculator Online

The CFH to PSI calculator is a handy tool used in various industries, especially in fields like engineering, gas distribution, and HVAC systems. Its primary function is to convert flow rates from cubic feet per hour (CFH) to pounds per square inch (PSI). This conversion is crucial for ensuring accurate pressure measurements in gas systems, where PSI is a common unit of pressure and CFH represents the flow rate of gas in cubic feet per hour.

Formula of cfh to psi Calculator

The formula used by the CFH to PSI calculator is:

psi = (cfh / 60) * specific_gravity * 0.413

Where:

• cfh: Flow rate in cubic feet per hour.
• specific_gravity: Specific gravity of the gas.

This formula takes into account the flow rate in CFH and the specific gravity of the gas to determine the corresponding pressure in PSI. It's a straightforward calculation but can be time-consuming if done manually. Hence, the calculator simplifies the process and provides quick results.

Table of General Terms

To assist users further, below is a table of general terms related to gas flow and pressure, which users may find helpful for quick reference:

Term	Description
CFH	Cubic Feet per Hour; a measure of gas flow rate
PSI	Pounds per Square Inch; a unit of pressure
Specific Gravity	Ratio of the density of a gas to the density of air
SCFM	Standard Cubic Feet per Minute; a standardized flow rate
PSIG	Pounds per Square Inch Gauge; pressure relative to atmospheric pressure

Example of cfh to psi Calculator

Let's consider an example to illustrate the practical use of the CFH to PSI calculator:

Suppose we have a gas flow rate of 500 CFH and a specific gravity of 0.6. Using the formula mentioned earlier, we can calculate the pressure in PSI as follows:

psi = (500 / 60) * 0.6 * 0.413 ≈ 3.475 PSI

So, a gas flow rate of 500 CFH with a specific gravity of 0.6 corresponds to approximately 3.475 PSI.
