An​ outdoor, rectangular pool on campus is 4.5 meters​ [m] in width and 7.5 meters​ [m] in length. You may assume the depth of the pool is constant. If the pool is filled with pure​ water, the total pressure probe at the bottom of the pool reads 16.5 ​pound-force per square inch​ [psi]. What is the volume of the water in the pool in units of kiloliters​ [kL]?     Length Force Mass Pressure 1 ft=12 in 1 N=0.225 lbf 1 kg=2.205 lbm 1 atm=101325 Pa 1 in=2.54 cm   1 slug​ = 14.5939 kg 1 atm=14.7 psi 1 m=3.28 ft   Density of water=1000 ​kg/m3 Surface pressure=1 atm

A company has several sensors in storage silos to detect the total pressure in the silos to ensure the tanks will not leak. Each tank is designed to withstand a maximum total pressure of 5.7 atmospheres​ [atm]. An engineer wants to use one of the silos to store liquid nitric​ acid, which has a density of 97​ pound-mass per cubic foot [lbm​/ft3​]. If the tank is filled to a depth of 90 feet​ [ft], how much surface pressure in units of atmospheres​ [atm] can be applied to the top of the liquid inside the tank without exceeding the maximum total pressure of the​ silo?
