The customer has a 200 ACFM pump installed which holds a vacuum level of 22" Hg and they want to increase the vacuum level to 26" Hg. To calculate the pump capacity required to bring the vacuum to a higher level, we convert the vacuum levels quoted to absolute terms: P 1 = 29.92 - 22 = 7.92" HgA; P 2 = 29.92 - 26 = 3.92" HgA; We use the ...

A rotary vane pump is a positive-displacement pump that consists of vanes mounted to a rotor that rotates inside a cavity. In some cases these vanes can have variable length and/or be tensioned to maintain contact with the walls as the pump rotates. It was invented by Charles C. Barnes of Sackville, New Brunswick, who patented it on June 16, 1874. There have been various improvements ...

The vertical windmill, with sails on a horizontal axis, derives directly from the Roman water mill with its right-angle drive to the stones through a single pair of gears. The earliest form of vertical mill is known as the post mill. It has a boxlike body containing the gearing, millstones, and machinery and carrying the sails. It is mounted on ...
