Fig. B.1 Various properties of liquid water including: viscosity (д, •), density (p, o), heat capacity (Cp, ■), thermal conductivity (k, □), a group of parameters used in the calculation of the Rayleigh number (Ra = [gxp2Cp/kp]ATL3 = CRaATL3, see the text for the definition of the parameters used to determine CRa, *) and the Prandtl number (Pr, д). The dimensions for each parameter are given in the equation and their magnitude on the graph can be ascertained by putting 0 °C in the equation. All the equations in the graph have the temperature T in °C. Data are from J. R. Welty et al., ‘Fundamentals of momentum, heat and mass transfer,’ Third Edition, John Wiley & Sons (1984).

Fig. B.2 Various properties of air including: viscosity (д, •), density (p, o), heat capacity (Cp, ■), thermal conductivity (k, □), a group of parameters used in the calculation of the Rayleigh number (Ra = [gxp2Cp/kp]ATL3 = CRaATL3, see the text for the definition of the parameters used to deter­mine CRa, *) and the Prandtl number (Pr, д). The dimensions for each parameter are given in the equation and their magnitude on the graph can be ascertained by putting 0 0C in the equation. All the equations in the graph have the temperature T in 0C. Data are from J. R. Welty et al., ‘Fundamentals of momentum, heat and mass transfer,’ Third Edition, John Wiley & Sons (1984).

Fig. B.3 Various properties of Therminol VP-1 including: viscosity (д, •), density (p, o), heat capacity (Cp, ■), thermal conductivity (k, □), specific enthalpy (H, *) and the Prandtl number (Pr, д). The dimensions for each parameter are given in the equation and the temperature T is in 0 C. The symbols are data given by Solutia Inc. while the lines represent the correlations to the data. Data are from the Dow Chemical Company.

Fig. B.4 Pressure-enthalpy (Mollier) diagram for water. Thick lines are isotherms (T, constant temper­ature) and thin lines, isentropes (S, constant entropy). The lines labeled %10, etc. are lines of constant quality which is a constant amount of gaseous water (vapor). The critical point is shown at the apex of the vapor-liquid envelope. Data are from International Association for the Properties of Water and Steam.

Fig. B.5 Pressure-enthalpy (Mollier) diagram for n-Pentane. Thick lines are isotherms (T, constant tem­perature) and thin lines, isentropes (S, constant entropy). The critical point is shown at the apex of the vapor-liquid envelope. Data are from Starling et al., ‘Geothermal binary-cycle working-fluid properties information,’ DOE Report # DOE/ID/01719-4.
