The airplane is traveling in a straight line with a speed of 300 km/h, when the engines a and b produce a thrust of ta 40 kn and tb- 20 kn, respectively. determine the angular velocity of the airplane in t -5 s. the plane has a mass of 200 mg, its center of mass is located at g, and its radius of gyration about g is kg 15 m ta=40 kn 8m tg = 20 kn 8 m

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.

An industrial centrifugal air compressor has 34 radial blades that has no pre-whirl. the tip speed of the blades is 300 m/s, and the radial component of the air velocity at the tip is 150 m/s. air is inducted at 101.3 kpa and a stagnation temperature of 305 k. the mass flow rate is 3 kg/s. consider the power input factor to be equal to 1.04 and a stagnation temperature at the compressor exit of 370 k, if the flow is isentropic. assume cp-1005 j/kg.k. find the power input to the compressor (in kw)
