The hysteresis behavior of the boiling curve becomes less pronounced as the difference between the minimum and maximum (critical) heat fluxes becomes small. Calculate the ratio of the maximum to minimum boiling heat fluxes for water, ethanol, refrigerant R134a, and refrigerant R22.
Which fluid has the greatest potential for the most severe hysteresis effect?
For which fluid is the critical heat flux largest?
The boiling occurs at atmospheric pressure on a large, horizontal surface.
