if 2000G of water tank is located on the roof and the height is 14feet,then what is the water pressure in 2' pipe down from tank to floor? thanks
 
You better have a very strong roof because 2000*8.5=17,000 lbs of water without the weight of the tank etc..

That pressure should be, assuming a 10 ceiling, 10 + 14=24*.433= 10.39 psi when the tank is filled to the max and less as water is used out of the tank. That also assumes the outlet of the tank is on the floor of the building.

The down pipe size makes no difference. The psi will be the same.
