COND_VISC
COND_LIBR returns the viscosity of lithium-bromide water solutions in units of W/m-K or Btu/hr-ft-F using the correlation published by:
DiGuilio, R.M., Lee, R.J., Jeter, S.M., and Teja, A.S., " Properties of Lithium Bromide-Water Solutions at High Temperatures and Concentrations - I Thermal Conductivity", ASHRAE Transactions, Paper 3380, RP-527, pp. 702-708, 1990
The COND_LIBR function requires three parameters. The first parameter is a string, either 'SI' or 'ENG' indicating the unit system. The second parameter is temperature in °C for 'SI' or °F (for 'ENG'). The third parameter is the weight percent of LiBr in the solution.
The valid range for this correlations is : 20°C < T < 190°C and 30% < X < 65%
Example:
K=COND_LIBR('SI', 90,55) "[W/m-K] thermal conductivity of a 55% weight percent solution of lithium-bromide water at 90°C"
