What is the pressure exerted by a 10-foot column of water in psi?

To find the pressure exerted by a column of water, you can use the formula that relates the height of the water column to the pressure it exerts. The pressure in psi (pounds per square inch) can be calculated using the formula:

[ \text{Pressure (psi)} = \text{Height (feet)} \times 0.4335 ]

Here, the height of the water column is given as 10 feet. When you plug this value into the formula:

[ \text{Pressure} = 10 , \text{feet} \times 0.4335 , \text{psi/foot} ]

Calculating this gives:

[ \text{Pressure} = 4.335 , \text{psi} ]

When rounded appropriately, this value is generally represented as 4.33 psi. Therefore, the correct answer accurately reflects the pressure exerted by the 10-foot column of water, confirming the choice provided. This calculation is foundational in understanding hydrostatic pressure, which is crucial for managing wastewater systems effectively.
