7.46. CHAPTER 7, PROBLEM 46 811 7.46 Chapter 7, Problem 46 Figure 7.23: Hydroelectric plant. Applying the approximate energy equation between the reservoir free surfaces (Points 1 and 2), we have p 1 ρ g + α 1 u 2 1 2 g + z 1 = p 2 ρ g + α 2 u 2 2 2 g + z 2 + h t + h L Now, the pressure is atmospheric at both Points 1 and 2 so that p 1 = p 2 .A l s o , u 1 0 and u 2 0 ,wh i le
