Abstract
A method of determining the average size of a plurality of pores on the external surface of an enhanced tube having subsurface channels connecting adjacent pores. A pressure measurement apparatus is positioned on a portion of the enhanced tube surface and regulated air supply pressure is blown into the pressure measurement apparatus whereby a portion of the air pressure escapes through the pores and subsurface channels. Accordingly, the difference between the supply pressure and the pressure lost across the pores and subsurface channels is a measurement of the pore size which correlates to the boiling heat transfer coefficient of the tube.
