Question

1) Although gas station owners lock their tanks at night, a gas station owner was the victim of theft because his employee had a key to the tank.

The owner of the gas station wants to bury the gasoline so deep that no vacuum pump will be able to extract it. He has hired a general contractor to dig the holes for the tanks. What is the minimum gasoline surface depth ℎ2 needed to prevent siphoning by any pump?

Assume the specific gravity of gasoline is 0.766 and that the tank is not sealed. (You can ignore the drop rate of the gasoline level inside of the tank.)

What is ℎ2 in Feet?

The gas station owner balks at the contractor's estimate. He neither has the funds nor approval from the city to dig that deeply. However, the contractor tels him that the best a thief could hope to have at his disposal is a 202‑mbar vacuum pump. Anything better would be enormously expensive. Given this information, how deep ℎ2 would the gasoline have to sit below the surface to keep it safe from thieves?

**Preventing Siphoning at Gas Stations: A Case Study**

Although gas station owners lock their tanks at night, a gas station owner was the victim of theft because his employee had a key to the tank.

The owner of the gas station wants to bury the gasoline so deep that no vacuum pump will be able to extract it. He has hired a general contractor to dig the holes for the tanks. What is the minimum gasoline surface depth \( h_2 \) needed to prevent siphoning by any pump?

Assume the specific gravity of gasoline is 0.766 and that the tank is not sealed. (You can ignore the drop rate of the gasoline level inside of the tank.)

\[ h_2 = \_\_\_ \, \text{ft} \]

The gas station owner balks at the contractor's estimate. He neither has the funds nor approval from the city to dig that deeply. However, the contractor tells him that the best a thief could hope to have at his disposal is a 202-mbar vacuum pump. Anything better would be enormously expensive. Given this information, how deep \( h_2 \) would the gasoline have to sit below the surface to keep it safe from thieves?

\[ h_2 = \_\_\_ \, \text{ft} \]
