Ammonia is used in many industrial applications. Hence, constructing the property tables for ammonia is important. With no experimental setup, the property tables of ammonia can be constructed using the thermodynamic relations from theoretical perspective. Lee Keslar equation of state is often used to perform the task. However, due to its complexity, Van der Waals equation of state is another alternative. Question 1 (100 marks) In the project, the theoretical methods will be used to construct the property tables for ammonia using the Van der Waals Equation of state. You are required to find out the specific heats of the Van der Waals gas before performing the calculation. Consider the Van der Waals gas obeying the equation of state: RT a where a and b are empirical constant to be determined assuming the critical point occur at inflection and stationary point on the pv diagram. The critical pressure and temperature of ammonia are 11.35 MPa and 405.5 K respectively. Assume the universal gas constant, R = 8.314 J/mol-K. Sketch the following graphs using reduced temperature as the parameter, T, = 0.85, 0.86, 0.88, 0.90, 0.95, 1.00, 1.10, 1.40, 2.00, and 5.00 for ammonia. a. Reduced pressure, p, versus reduced specific volume, vr. b. c. d. Compressibility factor, Z versus reduced pressure, pr Internal energy of departure, (u - u)+/RT versus reduced pressure, pr. Entropy of departure, (s* - s)+/R versus reduced pressure, pr. Use log scale to plot the axis for reduced pressure and reduced specific volume in the range of 0.1 to 10. For other axis, use the suitable range of plot to give the best fit of the graphs. e. Referring to the tables in appendix, construct the property tables of ammonia using Van der Waals equation. Compare and validate your results with the data from literatures as shown in the property tables in the appendix. You are required to present and defend your work during the presentation, and submit the assignment report.
