Consider a large chemical storage tank that is 100 ft in diameter and 25 feet tall. The tank is vented to the atmosphere to minimize explosion hazards. If the height of the liquid in the tank is 20 feet and the liquid has a specific gravity of 0.78, answer the following questions.
a. What is the pressure at the bottom of the tank in psi and in atm?
b. What is the force exerted by the fluid on the base of the tank?
