What efficiency are we rating? Gas per hour, weight versus output, efficiency of movement, efficiency of this unit versus another unit, 50x50 foot square covered with leaves or sand and rocks? Who cleans it fastest? Let me know if I'm getting close.lawnmaniac883 said:Efficiency?
You cannot measure peformance in psi. Not because the units arent powerful enough but because they really dont produce any pressure that could be measured with a psi gauge or whatnot. They move air, not pressurize it.
There might be something here. When the air hits something it transfers energy like the wind in a sailboats sail. The stronger the wind the more energy, the more energy the faster the boat moves. I'm not sure how to easily measure this though. I don't know if it will equate to PSI but its bound to be measured somewhere. However it's done it must be easily understood, small, unbiased, and able to be used by anyone.
Any sailboaters out there? This is all good. Keep it up.
