Package description

Package contents

• Function visc_dTp implements a function to compute the industrial formulation of the dynamic viscosity of water as a function of density and temperature. The details are described in the document visc.pdf.
• Function cond_dTp implements a function to compute the industrial formulation of the thermal conductivity of water as a function of density, temperature and pressure. Important note: Obviously only two of the three inputs are really needed, but using three inputs speeds up the computation and the three variables are known in most models anyways. The inputs d,T and p have to be consistent. The details are described in the document surf.pdf.
• Function surfaceTension implements a function to compute the surface tension between vapour and liquid water as a function of temperature. The details are described in the document thcond.pdf.
