KES EQUIPPED WITH SUPERCHARGING ENGINES. Let us use the above equations to evaluate the power delivered by the engine at 40,000 feet and 1,900 revolutions per minute. From figure 4 the temperature Tt is 376.5°. The value of f, equation (34), is 28.95. N^T^ is 1.2S5X10«. Hence the quantity… … Fig. 9. Quanfffy Coeff/'c/enf - q ffig. 7) is 0.67S, and the corresponding value of A, equation (36), is 0.2645. The pressuie ratio (fig. 6) is 2.251. The compressor intake pressure (fig. 4) is 14 cm. of meieury, and the car- buretor nressure is accordingly 31.5 cm. of meieury. The mechanical…
