The critical velocity of vapor flow from the heating surface 
in boiling is found based on the analogy of bubbling and boiling 
phenomena. The relation for the critical thermal load qcr is found 
from the assumption that this quantity corresponds to the maximum 
vapor velocity. The expression obtained in this work for qcr 
describes experimental data on the saturated boiling of water, 
ethanol, and benzene at different pressures.
