(Q1) A small reservoir based plant is planned in a remote location to supply water into a micro turbine to generate electricity. The height of water level in reservoir is 10 m. The micro turbine is to be located at ground level at a distance of 200 m from the reservoir. To generate sufficient power, the minimum head (total head) required at the turbine inlet is 9 m with the flow rate of 0.4 m3/s. The loss coefficient (KL) at the inlet to the pipe from reservoir is calculated as 0.4. Determine the minimum diameter of the cast iron pipe (roughness, e = 0.26 mm) required for the proposed design. Take following properties of the fluid: density (EGL). 1000 kg/m3, viscosity = 0.001 kg/m-s.

Q. No 3). A water supply pipe line is designed to supplying water to a nearby city. Determine velocity of water when it reach to a location 1.3 km from the pumping station where maximum head loss was found to be X m. Assume that pipe used is having diameter of Y cm and commercial steel pipe is used in the project. X= 2 Y= 169 Use Value of X and Y from following table

The suction water level is 5m above water pump center line and discharge water level is 25m above the pump center line. The total head loss at suction and discharge is 2m. If discharge is 0.01m3/s, find the horsepower needed to pump the water for 80% pump efficiency. ANSWER: 8.15 hp

A pump is needed to drain an excavation at a construction site. The excavation has alength of 50m, width of 50m, and a depth of 4m. The surface of the water in the excavation lies at adepth, H=3m, from the top the of the excavation. An old, radial flow, 1000W pump is immediatelyavailable for use; however, the total pump-motor efficiency, e, is only 50%. Estimate the drawdown inthe excavation in the first 4 hours of pumping.

A flow rate of 3 m'/s of water is available at a height of I 10 m at a project site. Due to losses in the sup- ply line, the head available at the inlet to powerhouse is estimated to be only 101 m of water. The leakage losses in the powerhouse are negligible. Mechanical losses account for 150 kW. Frictional losses in the rotor blades may be taken as 250 kW. The exit velocity of water from the turbines is 4.5 m/s. Calculate the hydraulic, mechanical, and overall efficiencies of the plant. The specific weight of water may be taken as 9810 N/m.
