1. Similar to the bubble growth in a conical cavity, the
bubble growth in a cylindrical cavity is shown in the figure. Verify the
accuracy of the plot of the inverse of bubble radius (1/r) versus bubble
volume.

2. Find the degree of superheat (Ts – Tsat)
for a horizontal flat plate in water at atmospheric pressure needed to cause
nucleation if cavity sizes of 5 µm are present in the heated surface.
