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?
Estimate teh excess solids production of an extended aeration process treating unsettled wastewater with a BOD of 200 mg/l and suspended solids concentration of 240 mg/l, assuming k=0.35.
A hole at the bottom of a fish tank releases water at a rate given by the free jet equation. The hole at the bottom has a .5" diameter. If the water level is desired to be at 2' high and be at steady state,
The casting has a mass of 3 Mg. Suspended in a vertical position and initially at rest, it is given an upward speed of V mm/s in 0.3s using a crane hook H. Determine the tension in cables AC and AB during this time interval if the acceleration is ..
