Question 36
CHNAT2 marksNeeds review
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 m² of heating area. The latent heat of vaporization and the density of vapour under the operating condition are 1000 kJ/kg and 1 kg/m³ respectively. The diameter of each bubble is 10⁻³ m. Assume that the entire heat supplied is used for vapour generation. The heat flux (in Watt per m² of heating area) is ______________ (rounded off to third decimal place).
