Design an irrigation system for part or all of the 18-hole golf course shown in Fig. P11.43. The requirements are as follows:
1. Place the sprinkler couplings at approximately 100-ft intervals along the fairway centerline. The flow rate from each sprinkler is to be 40 gal/min. A maximum of two sprinklers on each fairway are to be in operation at any time.
2. Place four sprinklers around the periphery of each green. The flow rate from each sprinkler is to be 40 gal/min. A maximum of three sprinklers on each green are to be in operation at any time. As an alternative to specifying the sprinkler flow rate, specify the loss coefficient across each sprinkler (e.g., try Kv = 35), and with successive trials, adjust it until the desired flow rate is achieved.
3. Water is to be pumped from the well shown. The maximum possible flow from the well is 2000 gal/min. Work with useful power in order to satisfy the system demand.
4.System pressure is to be 80 ±10 psi at all locations, and the design velocity in each pipe is not to exceed 5 ft/sec. Use smooth plastic piping and fittings throughout.
