What is the pressure at the bottom of a pressurized tank with a 20 ft liquid level?

A. 9.8 psi
B. 14.7 psi
C. 19.6 psi
D. 29.4 psi

Answer :

Final answer:

The pressure at the bottom of a pressurized tank can be calculated using the formula P = ρgh, where P is the pressure, ρ is the density of the liquid, g is the acceleration due to gravity, and h is the height of the liquid.

Explanation:

The pressure at the bottom of a pressurized tank can be calculated using the formula P = ρgh, where P is the pressure, ρ is the density of the liquid, g is the acceleration due to gravity, and h is the height of the liquid. In this case, since the tank is filled with liquid and not gas, we can use the density of the liquid to calculate the pressure.

Assuming the density of the liquid is constant, the pressure at the bottom of the tank can be calculated as follows:

P = ρgh
P = (density of liquid)(acceleration due to gravity)(height of liquid)
P = (density of liquid)(9.8 m/s²)(20 ft)
