A hydroelectric power plant uses Pelton-type turbines, in which multiple nozzles are used to accelerate the waterwhich is directed onto the turbine blades, which are exposed to an atmospheric pressure of 101.325 kPa. The water enters the nozzles with an absolute pressure of 500 kPa and a speed of 5 m/s, and the nozzle outlets are exposed to atmospheric pressure and have an internal diameter of 5 cm. Consider that the specific mass of water is 1,000 kg/m3. Determine the mass flow rate of water through each of the nozzles, and explain why the actual mass flow rate will be lower.
I am studying for an exam this week, and I want to check my steps and answers for this one problem. Air enters a nozzle steadily with a density of 2.21 kg/m^3 and velocity of 40 m/s and leaves at 180 m/s with a density of 0.762 kg/m3. If the nozzle inlet has an area of 90 cm^2, determine: a) The Volumetric flow rate at the in let (m^3/s) b) The Mass flow rate (kg/s) through the nozzle; c) The exit area of the nozzle (cm^2)
At a hydroelectric plant the difference in elevation between the surfaace of the water at the intake and at the tailrace is 183m (600ft). When the flow is 80 cfs, the friction loss in the penstock is 60 ft and the head utilized by the turbine is 460 ft. The mechanical friction in the turbine is 100hp, and the leakage loss is 3 cfs. Find (a) hydraulic efficiency; (b) volumetric efficiency; (c) power delivered to shaft; (d) brake horse power, (e) mechanical efficiency; (f) over-all efficiency.

Towards the inside of a cylindrical tank with diameter: D = 24 m, water flows through a tube 1 with a velocity v1 = 20 m / s and exits through tubes 2 and 3 with velocities v2 = 8 m / s and v3 = 10 m / s respectively. At 4 there is a vent valve open to the air from the atmosphere. (a) What is the speed with which the level rises of water in the tank? (b) what is the average velocity of the air flow at valve 4? assuming air is incompressible. Assume the following pipe diameters: D1 = 3 m, D2 = 2 m, D3 = 2.5 m, D4 = 2 m, consider that the density of water is: ρw = 103 kg / m3 , and the density of air is: ρa = 1.2 kg / m3
BEER with a density of 789 kg/m3 from a non-elevated open reservoir (P1=0 bars) flows before the pump at 0.75 m/s. The beer is pumped at a rate of 15 m/s to a 5 meter elevated tank with a pressure reading of 0.69 Bars. assuming zero Friction losses, Calculate the actual work if the pump's efficiency is just 44%. Calculate the theoretical and actual power in hp for a mass of 100 kg and a time of 1 minute of Beer.
Problem 5: A pressurized tank of water has a 10-cm-diameter nozzle at the bottom, where the liquid discharges to the atmosphere. The liquid level is 2.5 m above the outlet and the tank diameter can be assumed to be much larger than the diameter of the discharge nozzle. The air pressure in the space above the liquid is 250 kPa (absolute) while the atmospheric pressure is 100 kPa. Neglecting frictional effects, determine the rate of discharge (kg/sec) of liquid from the tank when the liquid level is 2.5m Air 250 kPa 25m 10 cm

Water in an enclosed tank is subjected to a gauge pressure of 2 x 10 Pa, appied by a compressed air introduced into the top of the tank. There is a small hole (diameter = 4 cm) in the side of the tank 5 m below the level of the water. Calculate the discharge rate.
The water level in a tank is 10 m above the ground. A hose isconnected to the bottom of the tank, and the nozzle at the end ofthe hose is pointed straight up. The tank cover is airtight, andthe air pressure above the water surface is 202.65 kPag. Thesystem is at sea level. Determine the maximum height to which thewater stream could rise.
(a) Water flows by gravity from one lake to another as illus- trated; the surface levels of the lakes differ by an eleva- tion of h= 50 ft.

(b) A pump is to be installed to pump the water from the lower lake to the upper lake with the same flow rate as above (Q = 80 gpm). If the amount of energy loss is assumed to be the same as in part (a), how much mechanical power must be supplied by the pump? Answer: (a) loss = 1600 ft-lb/slug, (b) Wpump = 2.0 hp
