SUMMARY

The discussion focuses on calculating the total pressure in a 22-ft onion tank filled with a hydrocarbon fluid of specific gravity 0.72. The calculation incorporates the hydrostatic pressure derived from the fluid height, which is 6.85872 psi, and adds the vapor pressure of 430 psi along with an additional 55 psi from nitrogen (N2). The final pressure in the tank is conclusively determined to be 491.85872 psi.

PREREQUISITES
  • Understanding of hydrostatic pressure calculations
  • Familiarity with specific gravity concepts
  • Knowledge of vapor pressure in fluid mechanics
  • Basic algebra for unit conversions and pressure summation
NEXT STEPS
  • Study hydrostatic pressure calculations in fluid mechanics
  • Learn about vapor pressure and its implications in fluid systems
  • Explore the effects of nitrogen gas on pressure in closed systems
  • Review specific gravity and its applications in engineering
USEFUL FOR

Engineers, fluid mechanics students, and professionals involved in pressure vessel design and analysis will benefit from this discussion.

I am concerned about adding the Vapor pressure of 430 psi to the equation. Should it be done??

1. Homework Statement


Calculate the pressure produced by a 22-ft onion tank filled with a hydrocarbon fluid (0.72 sg). Vapor pressure is 430. Add 55 psi N2 to the total. What is the final pressure?

2. Homework Equations


Height x 0.433 x specific gravity (according to the textbook) = pressure.

The Attempt at a Solution



22 ft. x 0.433 x 0.72 = 6.85872 psi + 430 psi + 55 psi = 491.85872 psi
