Water, at volume flow rate \(Q=0.75 \mathrm{ft}^{3} / \mathrm{s}\), is delivered by a fire hose and nozzle assembly. The hose of \(L=250 \mathrm{ft}, D=3\) in., and \(e / D=0.004\) is made up of four \(60-\mathrm{ft}\) sections joined by couplings. The entrance is square-edged; the minor loss coefficient for each coupling is \(K_{c}=0.5\), based on mean velocity through the hose. The nozzle loss coefficient is \(K_{n}=0.02\), based on velocity in the exit jet, of \(D_{2}=1\) in. diameter. Estimate the supply pressure required at this flow rate.
