	The efficiency is the product of the volumetric throughput multiplied by the pressure rise, all divided by the input power, all expressed in compatible units. __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856
