(OP)
What's the equation to cal vol of air flowed by rotation of fan ? I know dia. and pitch of fan blades and vol flow rate of air required but I'ld like to know what speed could be at that air quantity ?

The manufacturer of the fan can give you a fan curve or performance chart. For a given fan speed and system resistance, this information will give you the volume flow through the fan.
