Water is contained in a piston-cylinder assembly undergoes four processes separately, all started from an initial state where the pressure is p1, the temperature is t1, and the specific volume is v1:

process 1→2: constant temperature (isothermal) to p2 = 2p1; process 1→3: constant specific volume to p3 = 2p1;

process 1→4: constant pressure (isobaric) to v4 = 2v1; process 1→5: constant temperature (isothermal) to v5 = 2v1.

draw a p-v diagram and a t-v diagram for the water including the saturated liquid line and the saturated vapor line (dome).

the initial state (state 1) is at the saturated vapor state, note down state 2, 3, 4 and state 5 on both diagrams, and draw all processes (process 1→2, 1→3, 1→4 and 1→5)

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.
