∙ 12y agoThe diameter of the water column does not affect the pressure.
It is the height of the column that determines the pressure at the base.
(and also the barometric pressure and temperature).

Water column head is expressed either as the height of the column ... 6 meters here ... or else as the pressure at the bottom ... 58.842 kPa here. 'Kg' can't be a unit of water column head, and the diameter of the column is irrelevant.
Given that this stands out a mile as almost certainly a school homework question, to answer directly would be to make me complicit in cheating. So I will tell you how to calculate it, which would appear to be the point of the question: 1) The relationship between depth and pressure of water is linear. 2) If water X ft deep exerts a pressure of P lb/in2, then water of Y ft deep will obviously exert a pressure of P(Y/X) lbs/in2 Given thats information you can now solve the original question.
The column with the smallest diameter has greater pressure and the column with a larger diameter has less pressure.

The pressure at the bottom of a column of water depends on the height of the column, not its diameter. The pressure increases with increasing depth due to the weight of the water above. So, a taller column will result in higher pressure at the bottom.

Head pressure is created by a column (depth) of water in a container. Pipe is considered a container. Diameter is not a factor. The higher the column of water, the more psi it creates. Multiply column height of water by .434 to get psi of water.
"WC" on a gas line typically stands for "water column," which is a unit of measurement used to express pressure in a gas system. It represents the height of a column of water that would exert the same pressure as the gas being measured.
You need to know how high the water column is to calculate the pressure it exerts at its base! For example, a column of water 1 metre deep would exert a pressure of 9.81 kPa at its base (density x gravity x depth - 1000 * 9.81 * 1). This would be equal to approx 1.42 PSI.
Sea water will exert more pressure than river water due to its higher density. The pressure exerted by a fluid is directly proportional to its density, so sea water, being more dense than river water, will exert a greater pressure.

Yes, water exerts pressure on the hull of the submarine.
