(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.

Need detailed solution. During a trip to the beach (Patm = 1 atm = 101.325 kPa), a car runs out of gasoline, and it becomes necessary to siphon gas out of the car of a Good Samaritan. The siphon is a small-diameter hose, and to start the siphon it is necessary to insert one siphon end in the full gas tank, fill the hose with gasoline via suction, and then place the other end in a gas can below the level of the gas tank. The difference in pressure between point 1 (at the free surface of the gasoline in the tank) and point 2 (at the outlet of the tube) causes the liquid to flow from the higher to the lower elevation. Point 2 is located 0.75 m below point 1 in this case, and point 3 is located 2 m above point 1. The siphon diameter is 5 mm, and frictional losses in the siphon are to be disregarded. Determine (a) the minimum time to withdraw 4 L of gasoline from the tank to the can and (b) the pressure at point 3. The density of gasoline is 750 kg/m3. Answer: Δt = 53.1 s, P3 = 81.1 kPa

Example (1-2): A pump delivers water from a tank A (water surface elevation =110 m) to tank B (water surface elevation = 170 m). The suction pipe is 45 m long (friction factor, f = 0-024) and 35 cm in diameter. The delivery pipe is 950 m long (f = 0·022) and 25 cm in diameter. The head discharge relationship for the pump is given by Hp = (90 – 8000 Q²), where Hp is in metres and Q in m³/s. Calculate: (i) The discharge in the pipeline. (ii) The power delivered by the pump.
