• RE: Absolute or gauge pressure in hydropneumatic tank results?

    Yes, the gas pressure is expressed in terms of absolute pressure. This wiki article on modeling a hydropneumatic tank is a modeling reference for the element and should be able to help answer questions that you have on it.
  • Hammer results interpretation

    Hello I have modeled a raw water pumping line from a low to a high elevation using Hammer to compute up surge and down surge. My problem is even when using a hydronumatic tank i am getting negative pressures in the pressure envelope at the tail…
  • Hammer Analysis in Raw Water Transmission System

    I'm trying to evaluate the need for surge protection at new well locations in a raw water transmission system. I have a network of 6 wells all pumping to the water treatment plant. I'm new to Water Hammer and surge analysis so I'm just looking for some…
