Latent heat of vaporisation of water vs temperature
Liquid water from 0 to 100 °C at 1 atm — density, viscosity, specific heat, thermal conductivity and vapour pressure, all at the same state.
Latent heat of vaporisation in kJ/kg, from 0 to 100 °C. The chart and the table below are the same numbers; the table is the one you can copy.

Rows marked published land exactly on a source anchor and are the tabulated figure. The rest are this library’s interpolation between the two anchors either side — good enough to design with, and said out loud so you can decide that for yourself.
