815 ft/s. It ingests 1.2 times than into the core, which all exits through the ust. The fuel-flow-to-core airflow ratio is 0.0255. The exit densities of the fan and core are 0.00154 and 0.000578 slugs/ft, respectively. The exit pressures from the fan and core are 10.07 and 10.26 psia, respectively. The developed thrust is 10,580 lbf, and the exhaust velocities from the fan and nozzles? core are 1147 and 1852 ft/s, respectively. (a) Find the ingested air mass flow rate for the core and TSFC. (b) What are the exit areas of the fan and core 1.14 A turbofan operates at sea-level takeoff (SLTO). It has a bypass ratio of 8.00, and all of the secondary air exhausts through the fan nozzle. The fuel flow is 9.00 lbm/s. The exit areas of the fan and core are 6610 and 1500 in.2, respectively. The exit pressures from the fan and core are 14.69 and 14.69 psia, respectively. The exhaust velocities from the fan and core are 885 and and TSFC. 1255 ft/s, respectively. The core mass flow rate is 375 lbm/s. Find the thrust
