Expansion Tank Pressure Calculator

Formula

The formula to calculate the expansion tank pressure is:

\[ P_{tank} = \frac{H_t \cdot D}{144} \]

Where:

\(P_{tank}\) is the Expansion Tank Pressure (psi)
\(H_t\) is the Tank Head (ft)
\(D\) is the Density of Fluid (lb/ft³)

What is Expansion Tank Pressure Calculation?

The Expansion Tank Pressure calculation helps determine the pressure within an expansion tank based on the tank head and the density of the fluid. This is crucial for maintaining the proper operation of heating and cooling systems.

Example Calculation 1

Let's assume the following values:

Tank Head (\(H_t\)) = 30 ft
Density of Fluid (\(D\)) = 62.4 lb/ft³

Using the formula:

\[ P_{tank} = \frac{30 \cdot 62.4}{144} = 13.00 \text{ psi} \]

The Expansion Tank Pressure is 13.00 psi.

Example Calculation 2

Let's assume the following values:

Tank Head (\(H_t\)) = 50 ft
Density of Fluid (\(D\)) = 50 lb/ft³

Using the formula:

\[ P_{tank} = \frac{50 \cdot 50}{144} = 17.36 \text{ psi} \]

The Expansion Tank Pressure is 17.36 psi.
