-
High air-fuel ratio in gas turbines
-
The ratio of the volume of free air delivery per stroke to the swept volume of the piston, is known as
-
If p1, is the pressure of air entering the L.P. cylinder and p2 is the pressure of air leaving the L.P. cylinder (or intercooler pressure), then the ratio of cylinder diameters for a single acting, two stage reciprocating air compressor with complete intercooling is given by (where D1 = Dia. of L.P. cylinder, and D2 = Dia. of H.P. cylinder)
-
The ratio of the indicated power to the shaft power or brake power of the motor or engine required to drive the compressor, is called
