Five kg of water is contained in a piston-cylinder assembly, initially at 5 bar and 300°c. the water is slowly heated at constant pressure to a final state. the heat transfer for the process is 3560 kj and kinetic and potential energy effects are negligible.
determine the final volume, in m3, and the work for the process, in kj.

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.
