Question
Problem: Water flows through a turbine (T) from reservoir A to reservoir B, as shown in the figure. Determine how much power is the turbine able to generate and provide to the electric grid (turbine efficiency = 0.70) for a discharge Q of 2.2 m3/s? Also, sketch the energy grade line (EGL), indicating all energy losses, changes in slope, and abrupt changes. Make sure your figure can be interpreted even if it is not perfect. Assume the pipe material is cast iron with roughness Kg = 0.25 mm, kinematic viscosity v= 10-6 m2/s, the coefficient for entrance losses Ke = 0.5, and a= 1. ZA= 780 m A ZB= 80 m 1 = D1 = 1.5 m L1 = 690 m B T D2= 0.8 m L2= 4100 m
