A jet airplane is traveling 600ft/sec. The engine takes in 2400 ft3 of air, having a mass of 4.8 slugs, each second. The air is used to burn 0.20 slug of fuel each second. The energy is used to compress the products of combustion and to eject them at the rear of the plane at 1600 ft/sec relative to the plane. Find the thrust of the jet engine and the delivered power

Areheat rankine cycle operates with water as the working fluid. steam enters the first turbine at 8 mpa and 450°c and exits at 0.8 mpa. it is then reheated to 400°c before entering the second turbine, where it exits at 10 kpa. if the amount of work into the pump is 8.04 kj/kg and the net work per cycle produced is 1410.25 kj/kg, determine the thermal efficiency of the cycle.
