A new residential complex in Starkville will be supplied with2.674 ft3/s at a pressure of 3600
lb/ft2. The piping system will be connected to the main city supplyline (9360 lb/ft2), which has
10â€ft of elevation difference with the city line. Determine thecorresponding pipe size to connect
the apartment piping system to the city line. The design considersthe use of PVC (ks=5*10â€7 ft).
The system consists of 100â€ft of pipe, 4 threaded 90 elbows(kL=1.5), 10 threaded unions
(kL=0.08) and a swing check valve (kL=2.0). Consider water densityto be 62.42lb/ft3 and the
dynamic viscosity to be 2.34*10â€5 lb*s/ft2.
