Question
Water is being discharged from an upper reservoir to a lower reservoir through a turbine
(assume 80% efficiency), as shown in the figure. Find the power generated by the
turbine (in hp). The pipe is made of cast iron and has length 100 m and diameter 250
mm. Neglect minor losses. The reservoir elevations and desired flowrate are shown on
the figure. The kinematic viscosity of water is 1x106 m²/s. The roughness table and the
Moody Diagram can be found in the Appendix. (Ywater 9800 N/m³ and 1 hp = 746 Watts
or N.m/s)
