Water is the working fluid in an ideal rankine cycle. steam enters the turbine at 57.4 kpa and 537.7ºc. the pressure of the condenser is 95.7 pascal and the water comes out as a saturated liquid from the condenser. the net power generated by the cycle is 293 mw. the cooling water has an increase in its temperature from 15.5ºc to 24.4ºc. a) draw the cycle on a t-s diagram. b) the mass flow of steam. c) the heat, in watio / h, that is processed to the working fluid in the boiler. d) thermal efficiencye) the mass flow of the cooling water, in kg / s.

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.

Afull journal bearing has a journal diameter of 27 mm, with a unilateral tolerance of -0.028 mm. the bushing bore has a diameter of 27.028 mm and a unilateral tolerance of 0.04 mm. the l/d ratio is 0.5. the load is 1.3 kn and the journal runs at 1200 rev/min. if the average viscosity is 50 mpa-s, find the minimum film thickness, the power loss, and the side flow for the minimum clearance assembly.
