Water pressure and gravity in a storage cylinder

In summary, water pressure is the force exerted by water on its surroundings, and in a storage cylinder, it is determined by the weight of the water above and the force of gravity. The pressure increases with depth due to the increased weight of the water, and the shape and size of the cylinder can also affect it. Water pressure can be adjusted by changing the height, width, and amount of water in the cylinder. Ultimately, the water pressure in a storage cylinder affects the speed and force of the water flow.

Say you have a cylinder.

The cylinder is 6 inches in diameter and 10 feet high.

The cylinder has a floor at the bottom and is open at the top.

The cylinder is full of water. How much pressure is exerted on the floor of the cylinder?

Is it simply the weight of the water in the cylinder? How would you calculate?

Welcome to PF!

It is the weight of the water divided by the cross sectional area.

excellent thank you
 

What is water pressure and how does it relate to storage cylinders?

Water pressure is the force exerted by water on its surroundings. In a storage cylinder, the water pressure depends on the weight of the water above it and the force of gravity pulling it down.

Why does water pressure increase with depth in a storage cylinder?

Water pressure increases with depth in a storage cylinder because the weight of the water above increases as the depth increases. This is due to the force of gravity pulling the water downwards.

How does the shape and size of a storage cylinder affect water pressure?

The shape and size of a storage cylinder can affect water pressure in two ways. Firstly, a taller cylinder will have a higher water pressure at the bottom due to the increased weight of the water above. Secondly, a wider cylinder will have a lower water pressure at the bottom due to the larger surface area over which the weight of the water is distributed.

Can water pressure in a storage cylinder be increased or decreased?

Yes, water pressure in a storage cylinder can be increased or decreased by adjusting the height and width of the cylinder, as well as the amount of water inside. The greater the height and/or width, and the more water inside, the higher the water pressure will be.

How does water pressure in a storage cylinder affect the flow of water?

The water pressure in a storage cylinder determines the speed and force at which water will flow out of it. Higher water pressure will result in a faster and more forceful flow, while lower water pressure will result in a slower and weaker flow.
