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...

A closed, rigid tank fitted with a paddle wheel contains 1.6 kg of air, initially at 200oC, 1 bar. During an interval of 10 minutes, the paddle wheel transfers energy to the air at a rate of 1 kW. During this time interval, the air also receives energy by heat transfer at a rate of 0.5 kW. These are the only energy transfers. Assume the ideal gas model for the air, and no overall changes in kinetic or potential energy....

7.27 One kg of helium initially at 20°C and 1 bar is contained within a rigid, insulated tank. The helium is stirred by a paddle wheel until its pressure is 1.45 bar. Employing the ideal gas model with k = 1.67, determine the work and the exergy destruction for the helium, each in kJ. Ignore the effects of motion and gravity and let To = 20°C, po =...

PROBLEM 2 (35 points). An insulated, rigid tank whose volume is 0.5 m3 is connected by a valve to a large vessel holding steam at 60 bar, and 440°C. The tank is initially evacuated. The valve is open only as long as required to fill the tank with stream to a pressure of 40 bar. As this occurs, a paddle wheel adds 260 kJ per kg of work to the tank (where the kg mass for this work represents the...

Help please! A volume of 7.16 m 3 of air in a rigid, insulated container fitted with a paddle wheel is initially at 347 K, 3.6 bar. The air receives 539 kJ by work from the paddle wheel. Assuming the ideal gas model with c v = 0.66 kJ/kg • K, determine for the air: a) The amount of entropy produced, in J/K, and The final temperature in Kelvin

An insulated, rigid tank that is initially evacuated is connected by a valve to a nitrogen supply line. The nitrogen in the line flows at 30°C and 80 kPa. The valve is then opened and nitrogen flows into the tank until the pressure reaches 80 kPa; at which point the valve is closed. Using constant specific heats at room temperature (Cp = 1.039 kJ/kgK, Cv = 0.743 kJ/kgK, k. = 1.3984), determine the final temperature of the nitrogen in the...

M&S Problem 6.25. A rigid, insulated container contains 3 m? of air. The container is fitted with a paddle wheel and the air inside is initially at 295 K, 200 kPa. The air receives 1546 kJ from the paddle wheel. Assuming the air behaves as an ideal gas, determine (a) the mass of the air; (b) the final temperature in K; and (c) the amount of entropy generated, in kJ/K.
