Yes we can use limit state design for water tank design....
i think , because water tanks are more vulnerable structures and plus the tank is sometime overfilled and sometime empty, the pressure inside is so varying, its needs more safety precautions and as we all know working stress method assumes more safety factor than limit state design, which is an economical design, we prefer to use working stress method...
So you can use gravity rather then a pump to get water out of them.
When a pump is pumping water from a level that is below the pump it is called suction head. If the water to be pumped is at a level above the pump, it is positive head. The pump maybe pumping from the base of a tank to a higher level such as an elevated tank or it may be pulling water from a tank that is below the pump. The distance from the center of the pump to the top of the water level would be the foot of head. It takes 2.31 feet to make 1 P.S.I. So if it is 10 feet from the center line of the pump to the water level, you would have about 4.33 P.S.I. of head.
send me ur email , I can send my information to ur email about design and analysis storage tank with ansys research118118@yahoo.com

A storage tank is usually elevated, and feeds water by gravity. A suction tank relies on a pump to move water.

Yes, the pressure in the pipe is dependant of the height of the column of water above the point you are considering.
Each foot of elevation change is equal to 0.433 PSI of water pressure. Elevating the water tank 10 feet would add 4.43 psi.
pleas i want to know the proccedure of deisign of under ground concrete water tank
i know how to...mail me at piyush4567@gmail.com
he experimented with water colours, also in architecture and in tank design
I think oil will be less soluble in water at elevated temperatures.
Both are a means of delivering water at an increased pressure. The difference between the two is how they are installed. The water pressure in an elevated water tank system increases as the height of the tank goes higher. As a simple example, get a length of transparent plasticÊhose and fill it with water. Hold both ends of the hose at level then slowly raise one end higher than the other. Water will flow towards the lower end. For a booster pump system, there is no need for elevation. The pump itself is capable of increasing the pressure by pushing water fasterÊusing a hydraulic valve system.
It can be for many reasons. Usually it is because there is something coming off of the tank that will be gravity fed. They may also need to go and fill this tank and the fact that it is elevated makes it easier to transport.
