Question
In the figure below, there are 3 linked pipes in the system. The first pipe has diameter 2 in. is 125 ft long, f = 0.02, and has two 90 degree regular flanged elbows. This pipe expands to 6 in diameter, f = 0.023, and is 75 ft long when it enters the turbine. The 3rd segment of pipe is 3 in in diameter, 150 ft long, is cast iron, and has an open globe valve (K = 6.9). If the flow rate is 10 ft3/s and the water temperature is 68 degree F, what is the power extracted by the turbine? Power = pgQhr ft lb/s, 1 horsepower = 550 ft lb/s. Refer to the figure below. Water, rho = 1.94 slugs/ft3 and v = 1.1 Times 10-5 ft2/s, is pumped between the two reservoirs. Q = 2 ft3/s, the total pipe length is 400 ft, ks/D = 0.001. Kopen globe value = 6.9, and K half-open gate value = 2.7. What is the horsepower required by the pump? Power = pgQhp ft lb/s, 1 horsepower = 550 ft lb/s.Explanation / Answer
which one buddy? btw they are huge questions and can not be done in a single post.. the general energy principle is simple.. energy can neither be created nor destroyed.. it can only convert from one from to another like sound to heat.. kinetic to potential.. hope its clear :)
