The main difference between the old and new code is the method of design-earlier one is based on Working stress method and the present one is based on Limit states Design! Hence comparisons are difficult to make. Since you are conversant with IS 456, it may not be difficult for you to follow. I do not have the new codes here-I saw the Draft- but think that the tables for BM calculation remain the same. You have to use LSM equations for the design instead of WSM. Note that crack control is imp. in such structures. Hence the code prescribes Clauses for the same.
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...
send me ur email , I can send my information to ur email about design and analysis storage tank with ansys research118118@yahoo.com
role of national electric code in the design of electrical installation
Yes. If you change any fixture or hot water tank you must install a valve that limits the hot water delivery at the new fixture to 48C. If you change the hot water tank you must either put a valve on all fixtures except the diswasher and clothes washer or add a mixing vavle on the output of the tank.

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
In many American water heaters the cold water IN connection is now routed to the bottom of the tank (as opposed to both on top as used to be. ) .
Refactoring improves the design of code in many ways. Refactoring improves the design of code by taking a bad design and making it a good one and making the code easier to work with.
The country code and area code of Tank, Pakistan is 92, (0)963.

This depends on the design of the tank for under pressure. The vaccum breaker is then sized to slightly under the design under pressure. So in this case, the vaccum breaker will open before the design under pressure is reached to protect the tank.
You must have a pressure relief valve. I believe it is code nationally. I don't think you can buy a hot water tank w/o one. Expansion tank needed also if water meter has backflow preventer, check with local water authority if it does.
