Calculate the pressure produced by a ten foot onion tank, filled with a hydrocarbon fluid. (.72 s.g.) . Vapor pressure 200. Add 45 psi N₂ to total. What is the final pressure? A) 25.65 psi B) 2.48.1 psi C) 4.56 psi D) 8.89 psi

Question

Quizplus · Accepted Answer

The pressure due to the liquid column is calculated using the formula: Pressure = height x specific gravity x 0.433 psi/ft. For a 10-foot tank with a specific gravity of 0.72, the pressure is 10 x 0.72 x 0.433 = 3.12 psi. Adding the vapor pressure of 200 psi and the nitrogen pressure of 45 psi gives a total pressure of 248.12 psi.
