Problem 3: Civic Waterworks Consider the historic fountain in Ferril Lake in Denver's City Park. According to Friends of the Electric Fountain, it is powered by two 125 horsepower pumps, and it can spray water up to 65 feet above the lake surface. Part A Assuming the upward jet of water has a cross-sectional area of 0.050 ft² and the pump has an efficiency of n = 0.60, what electrical power is required to achieve the full 65 ft height? Part B Assume the fountain runs for 12 hours/day and for 3 months/year and electricity costs 10c per kilowatt-hour (kWhr). Use your result from Part A to calculate the annual electricity cost [S]. http://t

To develop maximum capacity it was proposed to install 2 turbines, one of which is 1.5 times the capacity of the other. Both turbine units are assumed to have efficiency of 85%. Determine (a) the total power developed, (b) what is the power developed by turbine #1 and by turbine #2 and (c) Rotative speed of each turbine unit assuming specific speed equal to 70 rpm.
Albert bought a portable device to pump his truck tyres. On the manual, he found out that the device is a single stage, single-acting air compressor. Air delivery for this device is 30 bar at a speed of 1500 rev/min. The atmospheric condition of his location is 87 kPa and 20 ˚C, with a FAD of 0.22 m2 /min. The clearance volume is 4% of the swept volume and the stoke/bore ratio is 1.3/1.Take “n” as 1.3, cp = 1.005 kJ/kg K, cv = 0.718 kJ/kg K Based on pictures below 1 which formula number will be used to evaluate the mass flow rate of air? 2 which formula number will be used to evaluate the delivery volume?

A steady stream of n-butanol is needed to be fed into the reactor at 40 ̊C. However, the inlet of the reactor is located 7.5 m above the reservoir tank. As such, a highly effective centrifugal pump (70% efficiency) is used for such a purpose. It was understood that the needed volumetric flow rate into the reactor is fixed at 20 m3/h. It was also noted that the n-butanol reservoir is closed but not pressurized, while the gauge pressure at the endof the discharge line is measured at 275 kPa. Given that the density of n-butanol is 810kg/m3. If the discharge pipeline was 5 cm in diameter, calculate: (i) The velocity of n-butanol at the discharge line. (ii) The total power input from the centrifugal pump. (iii) The power delivered to the n-butanol fluid.
3. A pump steadily circulates oil used for lubricating heavy machine tools. The volume flow rate and temperature of the oil are 300 gal/min and 104°F, respectively. At 104°F, the kinematic viscosity and the specific gravity of the oil are 2.15 x 10-3 ft² /s and 0.89, respectively. The pipe lengths are 25 ft for the 4-in diameter pipe and 75 ft for the 3-in diameter one. The Schedule-40 steel pipe has an average roughness element size of 0.0018 in. If all minor losses can be ignored, evaluate how much power (in a unit of horsepower) the pump delivers to the oil. 6 ft 22 ft Flow 15 ft Discharge line 3-in Schedule 40 Suction line 4-in Schedule 40 steel pipe steel pipe Pump
60 degree F water flows through a horizontal turbine. The water speeds at the turbine inlet and the turbine outlet are identical. The water gage pressure at the turbine inlet is 46.4 psi while that at the outlet is 12.2 psi. Assume water frictional losses through the turbine are negligible. Deterimine the shaft work rate in ft*lb per slug of water passing through the turbine. Answer with a positive number if mechanical energy goes into the water and a negative number if mechanical energy comes out of the water as it passes through the turbine.
