For a given production rate of metal removal, better tool life is obtained by using heavy feed and low speed.
Sorry, Flash.
Less horsepower per cubic inch of metal removal is required for heavier feeds (see the diagonal lines on the chart below.)
This also means fewer revolutions of the work
Even in the early-resistant U.S., we're beginning to site more wind farms. Lots of towers using lots of land. Wind power critics claim the land use is too high for the value received.

what would be the water evaporation rate in 'dry' air at 42 atm pressure and 2900 degree C from an area of 1 meter sq per hour?
It obviously will depend on many factors, but if there is a 'normal' range what it would be?
Thank you in advance
