Asteam power plant operates between the pressure limit of 3.0 mpa for the boiler and 50 kpa for the condenser. if the plant operates in an ideal rankine cycle with superheated vapor enters the turbine at 3 mpa and 450c, determine: a) the moisture content at the inlet of the condenser, b) the net work per unit mass of steam flowing, in kj/kg, c) the heat transfer to the steam in the boiler in kj per kg of steam, d) the thermal efficiency, e) the heat transfer to cooling water passing through the condenser, in kj per kg of steam flowing.

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.

Which of the following components of a pid controlled accumulates the error over time and responds to system error after the error has been accumulated? a)- proportional b)- derivative c)- integral d)- on/off.

Most leaks in reciprocating air compressors can be detected and minimized by: (clo4) a)-detecting leakage areas using ultrasonic acoustic detector. b)-tightening joints and connections c)-replacing faulty equipment d)-all of the given options
