The free surface effect occurs in tanks when they are partially filled with liquid, but it can also be relevant when a tank is empty. In an empty tank, there may still be residual liquid or sloshing from previous fills that can create a shifting mass. This shifting can affect the tank's stability and cause dynamic forces on the structure when the tank is in motion or subjected to external forces. Thus, even in an empty tank, considerations for the free surface effect are crucial for safety and structural integrity.

What is the effect of slack tank?

As the vessel rolls the fluid in any slack tanks can shift to the low side moving the center of gravity towards that side. This is called the free surface effect. When the CG shifts it reduces the righting moment making the vessel more unstable.

When an empty tank is filled with air, the air molecules move into the tank and exert pressure on the walls of the tank. This increases the air pressure inside the tank and causes the tank to become pressurized.


Does parking on a slope affect gas?

If you keep an almost empty gas tank, residue can build up and clog up your gas tank. Other than that, a parked car doesn't use gas, unless your car is left idleing, (with an almost empty tank). Then, the gas stays in the back part of the tank and the gas could'nt get to the carburator, so the car would, in effect, run out off gas.
