5.117 WILEY Water is supplied at 4.5 m/s and 415 kPa to a hy- draulic turbine through a 1 m inside-diameter inlet pipe as indicated in Fig. P5.117. The turbine discharge pipe has a 1.2 m inside diam- eter. The static pressure at section (2), 3 m below the turbine inlet, is 25 cm Hg vacuum. If the turbine develops 1.9 MW, determine the power lost between sections (1) and (2). P = 415 kPa Q = 4.5 m/s D = 1 m Section (1). Turbine 3 m Figure P5.117 = 25 cm Hg vacuum P2 D = 1.2 m Section (2)
