Lynn,

Following from previous post from your self, I'm looking at AIR FLOW and FUEL FLOW for my single rotor.

EG [40 cu" per face x 3 ( 7,500/3)]/1728 = 173.6 CFM( Air)/ 14.7 ( Ratio)= 11.8 cfm ( Fuel)

40x3x2,000/1728=138CFM( Air)/14.7( ratio)=9.44cfm( fuel)

Question,

1. how does one convert cfm to Gallons per minute?

2. how does one convert CFM to diameter of inlet?
