241 2. (25 p) Consider the design of a pumped-storage-hydro system located next to a pond. Suppose the demand is estimated to be 10 kWh/day with a peak demand of 3 kW. A tank is placed on a hilltop 100 ft above the turbine/generator. Connecting pipe runs 800 ft. a) Assuming an average of 15% head losses in the pipeline and 80% conversion efficiency for the turbine/generator, how many gallons of water needs to flow from the upper tank to...

3. A pump draws water at 15°C from a well through 10 m of 3 inch sch 40 steel pipe. The pump is 7 m above the water level in the well. The pump discharges the water -horizontally through 30 m of 3 inch sch 40 steel pipe to a sprinkler. There is one check valve (ball type), and three 90° standard elbow installed at various places in the system. The pressure into the sprinkler should be 500 kPa and...

A pumping system is designed to pump from a storage reservoir located at an elevation of 1015 feet. The pump elevation is 1005 feet. The pump discharge flowrate is 4500 gpm and the water temperature is 100˚F (1 atm). Between the storage tank and the pump is 30 feet of 14-in DIP pipe (f = 0.018) with one rounded entrance (kent = 0.05), and two 45 -degree bends (k45 = 0.30). What is the NPSH (in ft) for this system?...

A wind turbine is located 1000 m from the seashore and exposed to winds at 30 km/hr. The blades of the turbine are 20 m in length. In order to avoid lower wind velocity near the ground, the turbine tower is placed high enough so that the blades are at least 3 m above the boundary layer. What should be the height of the axis of the turbine? Use air properties at 10 C, and assume the boundary layer is...

Water is pumped from a well to a water tower (an above-ground reservoir) through a 330 ft long galvanized iron pipe (ε-0.0005 ft) with a 2-in diameter. The water surface in the well is 10 ft below the ground and the water surface in the tower is 60 ft above the ground. The water is to be delivered at a rate of at least 370 L/min. The sum of the minor loss coefficients is 2.1 a) Using the pump performance...

Water (p=998kg/m^3,
u=0.001Pa*s) flows from reservoir A to reservoir B through the
piping system shown. Each elbow has a minor loss coefficient of
1.2. Each valve has a minor loss coefficient of 3.2. The entrance
and exit are both sharp edged. Determine the flow rate L/min. You
now need to modify the piping system to increase the flow rate to
100L/min by reducing the length of the 25mm pipe. What must new
