If the single payment amount factor for a period of 5 years is 1.33822. What is the nearest value of the interest rate?

 A cast iron flywheel is rotated at a speed of 1200 rpm and having a mean rim radius of 1 foot. If the weight of the rim is 30 lbs. What is the centrifugal force? Use factor C = 41

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.

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
