Steam supplied as of dry saturated steam at pressure of 4mpa to a turbine. the condenser pressure is 3.5 kpa. sketch the cycle on a t-s diagram. determine: a) work ouput neglecting pump work b) work required for the pump. c) heat transferred to the water in the condenser and amount of cold water needed through a condenser if increases of water temperature is assumed as 5.5k d) heat supplied e) cycle efficiency, f) specific steam consumption g) for same steam condition, determine efficiency and specific steam consumption for carnot cycle.

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.
