What is the pressure created by a column of water 30 ft high?

To determine the pressure created by a column of water, you can use the formula for hydrostatic pressure, which is given by the equation:

[

P = h \times \rho \times g

]

where:

• ( P ) is the pressure (in psi),

• ( h ) is the height of the water column (in feet),

• ( \rho ) is the density of water (approximately 62.4 lb/ft³ for fresh water),

• ( g ) is the acceleration due to gravity (which is essentially equal to 1 for this calculation in terms of feet).

Using this formula, the pressure exerted by a column of water that is 30 feet high can be calculated as follows:

1. Convert the height to pressure using the density:

[

P = 30 , \text{ft} \times \frac{62.4 , \text{lb/ft}³}{\text{32.2 ft/s²}} \approx 30 , \text{ft} \times 0.4335 , \text{psi/ft} \approx 13.005 , \text{psi}
