Redneck in training said:Any abrupt change in geometry of the flow profile will cause turbulence at any velocity. The pressure drop is proportional to velocity squared. If the flow profile changes gradually and the flow remain laminar all pressure is recovered and there is no loss (in ideal circumstances). In real world there will be some small loss. Since elbows always cause turbulence they have significant effect on pressure drop.
I am wanting to take a old fork lift I have replace with a new one. Make it into a 8 foot log splitter by using the lift it is power up and down has any body some thing like that or dreamed of doing it. I have chop saw and all my firewood has to be 16 inch long.
