An ideal gas with a heat capacity ratio of k = 1.2 undergoes a compression in a piston-cylinder from v1 = 5l to v2 = 2l. the temperature also changes: t1 = 300k, t¬2 = 500k. determine
a) the entropy change of the process in kj/kmol-k and
b) whether the process could occur adiabatically.

You are making beer. the first step is filling the glass carboy with the liquid wort. the internal diameter of the carboy is 15 in., and you wish to fill it up to a depth of 2 ft. if your wort is drawn from the kettle using a siphon process that flows at 3 gpm, how long will it take to fill?

What is the major difference between thermoplastics and thermosetting plastics from the polymerization structure point of view?

Acircular aluminum shaft mounted in a journal is shown. the symmetric clearance gap between the shaft and journal is filled with sae 10w-30 oil at t 30°c. the shaft is caused to turn by the attached mass and cord. develop and solve a differential equation for the angular speed of the shaft as a function of time.
