Want to generate electricity with a inline turbine connected to a generator. Got a dam with a 22m damwall with a 200mm valve at the bottom. The waterlevel is 20m. If I connect a cone type of reducer to reduce the outlet to say 50mm and put the turbine somewhere on the line, connected to a 50mm pipe and fit a pipe online to let the water flow back into the dam, generating power 24/7 while not wasting any water. Can this be done by using the force/speed/volume of water to push the water to a higher level. If so what method should be used?
The pinion gear rolls on the gear racks. If B is moving to the right at 8 ft/s and C is moving to the left at 4 ft/s, determine the angular velocity of the pinion gear and velocity of its center A.
A 10 kg block is being pulled down a slope with an angle of 20 degrees and has a velocity of .2 m/s. Determine the force required
A low pass filter has a cut-off frequency of 5 kHz and a high pass filter has a cut-off frequency of 8 kHz. These two circuits are connected back to back in cascade to form an input-output system
Determine the operating speeds of the machine at which the machine's steady-state amplitude is less than 0.2 mm. Take keq = 3 EI/L3.
The fixture AC is designed with a screw adjustment to regulate the height of the 900 N load supported by the roller at A. The screw bears against a smooth surface at B. Determine the reaction forces at points B and C. Neglect the weight of the fix..

The wheel of radius r rolls without slipping and has an angular velocity w. Write an expression for the velocity of point A in terms of theta and show that the velocities of A and B are perpendicular to one another
A landfill is located 500 km from a river whose surface elevation is 40 m lower than the ground elevation at the landfill. After several years it is discovered that leachate from the landfill, with a COD of 1300 mg/L, is leaking into the river.
A hyetograph has a uniform rainfall intensity of 1.5 in/hr in the first hour, 2.0 in/hr in the second, and 0.75 in/hr in the third. Calculate the direct runoff (in inches) using the SCS method. Assume a curve number of 65.
Design the ramp for the highest design speed (to the nearest 5 mph) without exceeding a minimum D of 8.0. (Assume the PC of the horizontal curve is at station 15+00, and the vertical curve PVIs are at the PC and PT of the horizontal curve). Maximu..
