Hello,

I have a SS-304 storage tank with 1" insulation (ID=14 feet X 20 feet High and self supporting cone roof). I am using Tank software for analysis purpose. In Tank software, under external pressure analysis - specify external pressure (Pe)in lb/ft^2.

Please, Can some one explain regarding external pressure. What will be the value?

I am using -1.73 inch of water OR -8.999 lb/ft^2. Is it correct??

I appreciate it.

Thanks - Mayur
