CONFIDENTIAL 2/10 QUESTION 1: (45 Marks) As a chemical engineer working under Takahashi Water Sdn. Bhd., you are required to know the properties of saturated water for future reference in any material and energy calculations. Hence, basic thermodynamic properties of saturated water is retrieved from *Thermodynamics: An Engineering Approach" that authored by Cengel. By applying the linear algebraic equations method, find the temperature of saturated water (7) if the enthalpy of evaporation (hra) equals to 1841.71 kJ/kg. For such process, employ the 7 data between 215 - 225 C and assume the form of 2d-order interpolating polynomial. (Hint: use Naive Gauss elimination and simple fixed-point method (generate the Tic. from highest power T for convergence, initial guess = average T. Es = 0.15%) if necessary). Perform the computation for 2 different situations below: TABLE A-4 Saturated water Temperature table Enthalpy, kJ/kg J/kg Sat. Sat. Sat. Sat. Sat. Temp.
