A constant-volume tank contains 5 kg of air at 100 kPa and 327°C. The air is cooled to the surroundings temperature of 27°C. Assume constant specific heats at 300 K.
(a) Determine the entropy change of the air in the tank during the process, in kJ/K,
(b) Determine the net entropy change of the universe due to this process, in kJ/K, and
(c) Sketch the processes for the air in the tank and the surroundings on a single T-s diagram. Be sure to label the initial and final states for both processes.
The following stress state exists around a wellbore drilled in the Atlantic Ocean: sigma x = sigma y = 80 bar sigma zz = 100 bar tau xy = tau xz = tau yz = 0 Pw = 80 bar. Derive the general Kirsch equation (Aaddnoy version)

a rigid tank contains 2kg of saturated liquid and saturated vapor mixture 500kpa. what quality x do you need if you
The flow around a model of a turbine blade is investigated. The model is five times larger than the prototype. A maximum pressure of 4 psi is measured at the leading edge, a maximum velocity of fps is measured near the top of the blade, and a small d..
Carbon-dioxide gas at 3MPa and 500 K flows steadily in a pipe at a rate of 0.4kmol/s. Determine a) the volume and mass flow rates and the density of carbon dioxide at this state. If CO2 is cooled at a constant pressure as it flows in the pipe so that..
a well insulated piston-cylinder assembly is connected to an air supply line at 8 bar as shown in the figure. initially
A power cycle receives 1120 Btu by heat transfer from a reservoir at 1080o F and discharges energy by heat transfer to a reservoir at 280 o F. The thermal efficiency of the cycle is 68% of that for a reversible power cycle operating between the same ..
