Boiling curve equation
WebThe classical pool boiling curve is a plot of heat flux, q″, versus excess temperature, Δ T = Tw − Tsat. As the value of the excess temperature increases, the curve traverses four different regimes: (1) natural or free convection, (2) nucleate boiling, (3) transition boiling, and (4) film boiling. WebEquation. The Antoine equation is = +. where p is the vapor pressure, T is temperature (in °C or in K according to the value of C) and A, B and C are component-specific …
