What is the pressure at the base of a column of water 10 feet high?

To determine the pressure at the base of a column of water, you can use the hydrostatic pressure formula, which states that pressure (in psi) is calculated by multiplying the height of the water column (in feet) by the weight of the water (in pounds per square foot) and dividing by the conversion factor. Water weighs approximately 62.4 pounds per cubic foot.

The pressure at the base of a 10-foot column of water can be calculated as follows:

1. Calculate the weight of the water column: 10 feet * 62.4 pounds per cubic foot.
2. The pressure at the base can be calculated using the fact that 1 foot of water produces approximately 0.433 PSI.

So, with a 10-foot column of water:

10 feet * 0.433 PSI/foot = 4.33 PSI.

This means that at the base of a 10-foot high column of water, the pressure is 4.33 PSI. This confirms that the correct answer reflects the fundamental understanding of hydrostatic pressure and its relationship to the height of the water column.

Understanding these principles is critical for plumbing and related fields since it affects how systems are designed and function in real-world applications.
