Calculate the pressure on an Onion Tank

In summary, The pressure on an Onion Tank can be calculated by multiplying the height of the liquid in the tank by the density of the liquid and the gravitational acceleration. An Onion Tank is a type of collapsible temporary storage tank that is used for storing liquids such as water, oil, or chemicals. Calculating the pressure on an Onion Tank is important because it helps to ensure the tank is not overfilled and can withstand the weight of the liquid being stored. The pressure on an Onion Tank affects its stability by exerting a force on the sides of the tank. Factors such as the height and density of the liquid, temperature, atmospheric pressure, and tank material and design can all affect the pressure on an Onion Tank.

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

1. How do you calculate the pressure on an Onion Tank?

The pressure on an Onion Tank can be calculated by multiplying the height of the liquid in the tank by the density of the liquid and the gravitational acceleration (P = ρgh).

2. What is an Onion Tank?

An Onion Tank is a type of collapsible temporary storage tank that is used for storing liquids such as water, oil, or chemicals.

3. Why is it important to calculate the pressure on an Onion Tank?

Calculating the pressure on an Onion Tank is important because it helps to ensure the tank is not overfilled and can withstand the weight of the liquid being stored. This information is crucial for the safety and structural integrity of the tank.

4. How does the pressure on an Onion Tank affect its stability?

The pressure on an Onion Tank affects its stability by exerting a force on the sides of the tank. If the pressure becomes too high, it can cause the tank to burst or collapse, which can be dangerous and lead to spills or leaks.

5. What factors can affect the pressure on an Onion Tank?

The pressure on an Onion Tank can be affected by the height and density of the liquid being stored, as well as external factors such as temperature and atmospheric pressure. The material and design of the tank can also play a role in the overall pressure it can withstand.
