1.The two disks each have a mass of 25kg and are attached at their centers by an elastic cord that has a stiffness of k = 1.6kN/m . Determine the stretch of the cord when the system is in equilibrium

2.Air mass of 4 kg of liquid water is cooled from 90c to 10c under a constant pressure. Determine the change in its entropy, assuming the process to be reversible.

3.An idealized porous medium consists of a horizontal straight capillary tube of length L and radius r. The medium contains a wetting phase in equal proportions. Calculate the numerical value of the Leverett J- function for this idealized porous medium. Assume the wall thickness of the capillary tube to be negligible small.
