In the figure shown below there are 125 ft of 2 -in pipe, 75ft of 6 -in pipe, and 150 \mathrm{ft} of 3 -in pipe, all cast iron. There are two 90
elbows and an open globe valve, all flanged. If the exit elevation is zero and the elevation at A is 100 ft, what horsepower is extracted by the turbine when the flow rate is 0.16 
of water at 
? For water at , take 
and 
slug/ft.s. For cast iron, 
. For Re=113500,37800, and 75600 , take f 
0.0314,0.0266, and 0.0287 respectively.
The minor loss coefficients are as follows:
sharp 2" entrance: K=0.5; two 2" 90 elbows: K=2(0.39)
2" sudden expansion: K 0.79 ; 3" open globe valve: K 8.5
The power extracted from the turbine is ____ hp.
