Water - Thermal Diffusivity vs. Temperature and Pressure

Calculate and display thermal diffusivity of water at varying temperatures and pressures (1, 10, and 100 bara). Thermal diffusivity (α) is the rate of heat transfer through a material, calculated as k / (ρ × CP), where k is thermal conductivity, ρ is density, and CP is specific heat capacity.
