Equations/Symbols:

Calculate:
Insert saturation temperature (Tsat), mass velocity (G), heat flux (q), vapor quality (x), tube diameter (D), inlet vapor quality (xin) and press 'Calculate'.
Fluid: Tsat (K): G (kg/s/m2): q (W/m2): x (-): D (m):
xin (-): [used only for post-dryout heat transfer coefficient in Tibirica et al. 2017]
