Hydraulic Calculation: Water Storage Tank

API 650 (Chapter 3 desing) this Standard is for oil storage but can be applied to water storage. WP

You need more aptitude. Study from author R.S Agarwal

1 foot of water head = .43PSI.

Please obtain a copy of American Water Works Association (AWWA) Standard ANSI/AWWA D-100, as well as API Standard 650.

Also, obtain the abstract: "Seismic Analysis and Design of Steel Liquid Storage Tanks", by

Lisa Yunxia Wang, California State Polytechnic University at Pomona.

Most water storage tanks fit in one of two categories.

1. Pumped: You must determine required capacity of tank, and flow rate/pressure for pump.

2. Non-pumped: You must determine required capacity of tank, and tank elevation. Start at most hydraulically remote location and use Hazen and Williams formula to determine line losses back to tank outlet. Add required pressure at remote location to line losses (minimize losses with stepped/larger pipe). Elevate tank (see post 4) to required height.

This is a very simplistic description, but is what the basics smell like.
