Air enters the compressor of a simple gas turbine at p1= 14 lbf/in.2, t1 = 520degreer, and a volumetric flow rate of 10,000 ft3 / min. the isentropic efficiencies of the compressor and turbine are 83% and 87%, respectively. the compressor pressure ratio is 14 and the temperature at the turbine inlet is 2500 r. on the basis of an air-standard (not cold air-standard) analysis, calculate the thermal efficiency of the cycle. the net power developed, in btu/h.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
