SUMMARY
The pressure at the bottom of a cylindrical water tank can be calculated using the formula P = ρ h g, where ρ is the density of water (62 pounds per cubic foot), h is the height of the water (6 feet), and g is the acceleration due to gravity (32 ft/s²). This calculation yields pressure in pounds per square foot, which can be converted to pounds per square inch by dividing by 144. The maximum pressure in this scenario, with a tank holding 1000 gallons of water, is approximately 0.125 atmospheres, equivalent to about 1.75 psi.
