Vapour bubbles are formed in the nucleate boiling regime at a frequency of 10 bubbles per second per nucleation site. There are 100 nucleation sites per 
of heating area. The latent heat of vapourization and the density of vapour under the operating condition are 
and 
respectively. The diameter of each bubble is 
. Assume that the entire heat supplied is used for vapour generation. The heat flux (in Watt per of heating area) is 
(rounded off to third decimal place).
