III. A 3.5 in3 hydraulic motor has a mechanical efficiency of 0.61 and a volumetric efficiency of 0.73. It produces 650 lb in of torque at 1220 rpm. System flow is provided by a piston pump that has a theoretical flow rate of 42 gpm and a mechanical efficiency of 0.71. The pump is driven by horsepower and kilowatts required to operate the system. What is the overall efficiency of the system? an electric motor with a 0.71 efficiency. Find...

The system below uses a centrifugal pump to circulate water at 19°C, having a vapor pressure of 2320 Pa, from a low reservoir to a higher one through a cast iron pipe with a diameter of 35 cm and surface roughness of 0.25 mm. The minor head losses upstream of the pump are represented by EK1 = 0,6 and downstream by & K2 = 7. After several months of usage, it is noticed that the installation is noisy and consumes...

(100 points) Water at 25°C is pumped at a rate of 0.075m'/s from a reservoir 20m above a pump to a free discharge (this means discharged to atmosphere) 35m above the pump. The pressure on the intake side of the pump is 150kPa and the pressure on the discharge side of the pump is 450kPa. The pipe between the reservoir and the pump is 3 meters of 5in diameter cast iron. From the pump to the discharge the pipe is...

Please answer ALL parts.
A phonograph turntable driven by an electric motor accelerates at a constant rate (i.e., constant angular acceleration) from 0 to 33.33 revolutions per minute in 2 minutes. The turntable is a uniform disc of mass 1.5 kg and radius R = 13 cm, as indicated in the figure. The radius of the driving wheel is r = 2.0 cm. What is the torque required to drive the turntable at this angular acceleration? If the driving wheel...

The Nissan Leaf is an all-electric car powered by a 107-hp electric motor and a lithium-ion battery that stores 24 kWh and produces 394 V at its terminals when fully charged. The Leaf's battery can charge at the rate of 3.3 kW from a standard 120-V power outlet, at 6.6 kW from a 240-Voutlet, and at 44 kW using a special 480-Vcharge. The Leaf's fuel economy is 3.38 miles per kWh, the equivalent of 114 miles per gallon in a...

D Question 3 5 pts A standard electric motor is rated at 10 horsepower (HP) and costs $800. its full-load efficiency is specified to be 87%. A newly designed, high efficiency motor of the same size has an efficiency of 93%, but costs $1,200. It is estimated that the motors will operate at a rated 10-HP output for 2,500 hours a year, and the cost of energy will be $0.07 per kilowatt- hour. Each motor is expected to have 12-year...
