Also, I want to see static pressure on the standpipes. so I did the standpipe calculation and I have rated pressure of 280 psi and from hydra calc. I have my pump churn pressure of 310 psi , now is there is a way in hydra calc where I can calculate static pressure. I don't want to do manually by adding or subtracting pressure looses from churn pressure. Please advise
Hi George, you have shown city connection and pump in the the calculations . Your pump is connected to base node when you are putting the water supply your pump needs to be connected at base not to the city. I am struggling with the calc I am working on , I want the pump to be connected with base because my run is first city connection from that I have backflow and then pump. So we we do it in hydra calc program
Shouldnt the pressure at HSE1 be 100 psi? Based on the 2.5" hose outlet size this is a class 1 system and per NFPA 14 Section 7.8.1 the minimum residual pressure of 100 psi at the most hydraulically remote 2-1/2" outlet.
Yes, thank you. The point of the video was to show you how to enter the values. I used outdated requirements but that shouldn't take away from the point of the video.
