Reconsider Prob. 3-122. Using EES (or other) software, investigate the effect of the surroundings temperature on the final equilibrium pressure in the tanks. Assume the surroundings temperature to vary from -10 to 30°C. Plot the final pressure in the tanks versus the surroundings temperature, and discuss the results.
EES Problem 3.122 is reconsidered. The effect of the surroundings temperature on the final equilibrium pressure in the tanks is to be investigated. The final pressure in the tanks is to be plotted versus the surroundings temperature, and the results are to be discussed.
Analysis The problem is solved using EES, and the solution is given below.
