2 140 pt) Reversible Adiabatic Expansion of Nitrogen. Nitrogen expands reversibly in an insulated cylinder fitted with a piston. The N2 is initially at 500K and 5 bar pressure and expands to a final pressure of 1 bar. Determine the final temperature T of the N2 (in K) as well as the work done in the process W (mol), assuming N2 to be in the ideal gas state. Heat capacity, Cp is equal to a constant at 3.560R.

An initially empty, well insulated, rigid tank with a volume of 2 m3 is fitted with a mixing device. The tank has two inlets and zero outlets. One inlet is water at 1 MPa and 600◦C while the other is saturated liquid water. Both enter the tank slowly. If the amount of work done by the mixing device is 300 kJ, what must the temperature of the saturated liquid water be if the same mass is added through both inlets...

Problem 1. Consider a well-insulated tank with constant volume, V. The tank is initially at vacuum ("State 1", mi-0). Surrounding the tank is an ideal gas, with constant cv and k and gas constant R. The pressure Pin and temperature Tin of the ideal gas surrounding the tank are constant. A very tiny hole is punched into the tank and air fills the tank with a time-dependent mass flow rate, mi(), until...

Problem 3-2 A rigid, well-insulated tank consists of two compartments eparated by a valve, one being twice the volume of the other. Initially, the smaller compartment contains 10 kg of nitrogen at 6 bar and 100°C, while the larger one is evacuated. The valve is opened and the gas expands to fill the total volume, eventually achieving an equilibrium state. Calculate: a) The final temperature, in K. b) The final pressure, in bar, c) The total exergy destroyed, in kJ...

A rigid, insulated tank fitted with a paddle wheel is filled with water, initially a two-phase liquid-vapor mixture at 200 kPa, consisting of 0.04 kg of saturated liquid and 0.04 kg of saturated vapor. The tank contents are stirred by the paddle wheel until all of the water is saturated vapor at a pressure greater than 138 kPa. Kinetic and potential energy effects are negligible. For the water, determine...
