Lynn,
Following from previous post from your self, I'm looking at AIR FLO= W=20 and FUEL FLOW for my single rotor.
EG [40 cu" per face x 3 ( 7,500/3)]/1728 =3D 173.6 CFM( Air)/ 14.7=20= (=20 Ratio)=3D 11.8 cfm ( Fuel)
40x3x2,000/1728=3D138CFM( Air)/14.7( ratio)=3D9.44cfm( fuel)
Question,
1. how does one convert cfm to Gallons per minute?
2. how does one convert CFM to diameter of inlet?
