How much head pressure does a 10-foot high deaerator tank have?

To determine the head pressure of a 10-foot high deaerator tank, we utilize the fact that water exerts pressure due to its weight, which can be calculated using the relationship between height and pressure. The pressure at the bottom of a column of water can be found with the formula:

Pressure (psig) = height (feet) × 0.433

Here, the height of the deaerator tank is 10 feet. Therefore, we calculate the pressure as follows:

Pressure = 10 feet × 0.433 psig/foot = 4.33 psig

This calculation shows that the correct head pressure for a 10-foot high deaerator tank is indeed 4.33 psig. Understanding this concept is critical in plant operations, as it relates to the management and calculation of pressure in various systems, ensuring safety and efficiency in handling water and steam systems throughout the facility.
