Draw the right diagram for the problem. Show complete solution.
Water at 60 F from a lake through 500 ft if 4in ID cast iron pipe at a water turbine 250 ft below the surface of the lake. After flowing from the turbine, the water is discharged into the atmosphere through a horizontal 50 ft section of the same pipe. The turbine power output is 10hp when the water in the discharged pipe is flowing at 5 ft/s.
a. What is the turbine efficiency defined as the actual power output of the turbine divided by the power output that would be withdrawn if there are no friction within the turbine?
b. If the turbine were by passed, what would be the flow rate of water through the 500 ft of 4in pipe?

- A fire starts in an apartment building in downtown Boston. When the firefighters arrive, they immediately get to work putting out the fire using a fire hose. The water for the fire hose is provided by a fire hydrant at ground level. Assume that the velocity of the liquid coming from the fire hydrant is 1.6 m/s, and that the pressure at the hose nozzle is atmospheric pressure (101000 Pa). a. The firefighters start with the ground floor, so there is no change in height between the fire hydrant and the hose nozzle. If the velocity of the water coming out of the nozzle is 12.8 m/s, find the pressure at the fire hydrant in units of Pa. b. After the ground floor fire is put out, another fire is spotted on another floor. A firefighter carrying the hose is lifted on a platform to the same height as the fire, which is 44.35 m above the ground. Assuming that the pressure found in part a) remains constant, what would be the new velocity of the water coming out of the nozzle at this new height?arrow_forwardA 150 mm diameter penstock supplies water to a turbine under constant head of 30 m.a.
