I am designing an apartment building located in Washington. Following are the design data:
Total WSFU: 1062
Total Supply Demand: 215gpm
Daily Service Pressure (Min): 60psi
Water Meter (Pressure Loss): 10psi
Min. Residual Pressure (at furthest point): 8psi
Static Pressure: 31.82psi
Available Pressure/Frictional Losses: 10.18psi
Avg Permissible Frictional loss per 100ft: 5.01psi
Dia of Building Supply: 3inch
Pipe Material: CPVC
UG Tank Dimension: 2170cubic feet
Air Height: 2.32feet
I am not sure how to choose hydro-pneumatic pumping system based on these data. Please help me!
