A turbofan operates at sea level and moves at 893 ft/s. It ingests 150 lbm/s

of air into the core and 2.2 times this amount into the fan, which all exits

through the fan exhaust. The fuel flow is negligible. The exit areas ofthe fan

and core are 336 and 542 in.2, respectively. The exit pressures from the fan

and core are 14.7 and 15.8 psia, respectively. The exhaust velocities from

the fan and core are 2288 and 1164 ftJs, respectively. Find the thrust. What

proportions arise from the fan and core?
