1). The van der Waal equation of state for a vapor is (P+) (v - b) = RT Where P is the pressure (Pa = N/m²), v is the specific volume (m³/kg), T is the temperature (K), R is the gas constant (J/kg-K), and a and b are empirical constants. Consider water vapor, for which R = 461.495 J/kg-K, a = 1703.28 Pa-(m³/kg)³, and b = 0.00169099 (m³/kg). Equation (F) can be rearranged into the form Pv3 (Pb+RT)v² + avab = 0 Calculate the specific volume v for P = 10,000 kPa and T = 800K. Use the ideal gas law, Pv=RT, to obtain the initial guess (or guesses). Present the results in the format illustrated in the examples
