[SIZE="3"] And you can try the following: On entering each group of two spiral you put one restriction,identical This ensures equal pressure to entry for each group of two spirals,therefore equal flow.

[SIZE="3"] 1000Kg = 1 tonne. Is a unit of mass, not force. (1pound=0.45kg) http://en.wikipedia.org/wiki/Kilogram" For force: 1Kgf = 1g N = 9.81 N (10N). g = gravitational acceleration (constant) http://en.wikipedia.org/wiki/Newton_(unit)" From momentum conservation law. m1V1=m2V2...

rotary piston-engine [SIZE="3"] Four-stroke engine has the following losses: 30% of energy is lost through cooling,40% is lost through the flue gas discharge and 8% mechanical losses and incomplete combustion.Only 32% of energy goes to the wheels.I try to eliminate these losses. The first...

[SIZE="3"] Movement of air it gives the sensation of coolness. Hurry evaporation, which consumes energy, so it cools. (When something is hot, you blow over it.:smile:)

[SIZE="3"] What is the own frequency oscillation of the system?(Response to a unit impulse?)

[SIZE="3"] I have learned systems theory for three years.I have forgotten a lot.Field is very broad. Would be best to search the library after the University cours of your professor. Maybe this will help...

I think a specialist with the possibility of execution,should complete the "rotary piston", in weeks.I, alone, would take years.Too much! A former colleague, mechanical engineer(sewing machine specialist), made the drawing of execution in 20 hours.I can not do.Execution on video you see is...

I am confused, or I do not understand well. All I found on yield, yield is related to an ideal model.Says nothing about the ideal model. Where can I find an energy balance.Something like this: In a hydropower, energy consumption in time t, it is E1= Qght Q is flow , g is g-force,h is water...

Thank you Jack,is useful and I have to study. Conclusion at first sight: the most efficiencies is bent axis motor. I think the rotary piston reaches at these performances. The main advantage is simplicity, reliability, low price.I also believe is more linear. His performance will not depend...

I have some questions. How is the turbine hydraulic efficiency? How depends on the pressure supplied? How is the efficiency of water pumps (hydrophore) used to supply drinking water the towns where are the three stages of the turbine to pressurize? (which is the word correctly, yield or...

No. When force is along the radius rod,torque is zero, no matter how it is force. (upper dead point). From this point of view, the torque is maximum when the force is perpendicular to the radius rod.And then decreases up to zero. (Lower dead point) Is a sinusoidal variation. Adds force...

But if working with liquid? As pump or hydraulic motor?

For a long time I wanted to ask someone:In the section where green arrow:between the two blades.Is a variable volume compartment during rotation.There occurs what is there? There is no valve. http://en.wikipedia.org/wiki/File:Rotary_vane_pump.svg" I am convinced that a pump or a hydraulic...
