Film coefficients are presented for sodium -potassium alloy (44 wt.% K) boillng on a horizontal surface. The heat transfer at the boillng surface was calculated by subtracting the heat loss to the surroundings from the electrical input to the heater. Temperatures in the boiling liquid and the vapor space above it were also determined. The best temperature differential for computing the heat-transfer coefficients was found to be the difference between the boiling surface temperature and the equilibrium boiling point of the sodium-potassium alloy at the pressure of the vapor space. A correlating equation was derived statistically for heat velocity as a function of pressure and temperature differential. (auth)
