Been asked to verify a 2" underground supply will work for a NFPA-13 Dry system for a small Patio/Bar. Water supply is good, S=114 / R=106 / F=1556. Preliminary numbers I've ran show a system demand of 324gpm @ 46psi. That's assuming a 10psi loss for underground pipe (BFP is 10 as well), the loss for 2" underground is the part I'm not real comfortable about. Any thoughts?
