Complete the property table for water below. Use only the Thermodynamic Property Table for Water referring to the Smith, Van Ness and Abbot Thermodynamics textbook. P [kPa] V [m³/kg] H[ kJ/kg] T[°C] Phase Description X 500 Saturated liquid 171 2044.5 300 0.8 Note that x refers to the "quality" or the mass fraction of the water in vapor phase. If the system is composed of pure liquid water, x = 0. If the system is composed of pure gaseous steam, x = 1. The volume of a liquid/vapor system can be determined using the following equation. V = Vj + x(Vg-Vj) V - volume of saturated liquid water Va - volume of saturated gaseous steam Similar calculation can be done for other properties such as internal energy, entropy, and enthalpy. H = HỊ + x(Hg-H) Under phase description, indicate whether the system is composed of saturated liquid, saturated vapor, superheated vapor, or liquid-vapor mixture. Also note that when pressure is given, it is more advisable to use the Superheated Steam Table than…

(a) The ideal gas equation of state is a fairly simple expression of the relationship between the physical properties of a gas. In Module 4, we will consider some other equations of states, one of which is the van der Waals equation of state, (? + a n2/ v2) (V-nb)=nRT where a and b are constant coefficients for a given substance, and P, V, T, and n have their usual meaning. Find the partial derivative (P/T)v for this equation of state . b) Mathematically, it is known that for three variables that are related to one another (as P, Vm, and Tare here) by a function (or equation of state), one can show                                     (??/??)z (??/??)x (??/??)y =−1 (note the cyclic variation of the three variables).Using this relationship, and the definitions of kT(coefficient of isothermal compressibility) and a (coefficient of isobaric thermal expansibility), find a simple equation relating the van der Waals parameter, b, to Vm, a, and kT. (For a discussion of this sort of…
