    Head loss through freewheeling blower?

    All, Thanks for your thoughts. Freewheeling means pretty much what BigInch said. In this particular case I am looking at a draft blower downstream of a micro turbine. The sole function of the draft fan is to make up for ducting losses, normally the micro turbine does not require a blower on...

    Hello All, Was wondering if anybody knows of a method to estimate head loss through a freewheeling centrifugal blower given the performance curve when the blower is running? Seems to me there should be a relationship or rule of thumb to relate this to the powered performance curve. Thanks for...
