How do you calculate the static head in a force main with a high point in the line?
For example, the suction water surface is at Elev. 0', the discharge water surface elevation is at Elev. -10' and there is an intermediate high point with an Elev. of 10'. Note, there is a combination air...
I understand that the temperature of the pumped fluid will affect the pressure rating of HDPE pipe force main. The lower the temperature the better the pressure rating. At 73 degrees (temperature at published HDPE pressure rating) I am just slightly below the pressure rating I need. I ASSUME...
For purposes of force main design what temperature should be assumed for raw sewage? Metcalf & Eddy says 50-70 degrees F depending upon location. The area in question is southeastern U.S. Does anyone know where I can find more specific data on sewage temperature?
Thanks.
What are the recommended min. and max. velocities for the vertical section of pump discharge piping in a sewage lift station. I read >8.5 fps from one source. Any recommendations? Thanks for the help.
