Calculate the peak heat flux for nucleate pool boiling of water at 300 kPa pressure and 110°C on clean copper.
GIVEN
? Nucleate pool boiling of water on clean copper
? Pressure = 3 atm
? Water temperature (Tw) = 390°C
Find
? The peak heat flux (q"max)
ASSUMPTIONS
? Steady state
PROPERTIES AND CONSTANTS
From Table 9.2, the surface tension at 133°C (o) = 0.0522 N/m
The maximum heat flux for water at saturation temperature is given by Equation (9.4)
The maximum heat flux for a subcooled liquid is given by Equation (9.5)

Consider a rope hung from the top of a tall ceiling to the ground. Someone sets up waves from the bottom of the rope and watches as they propagate up the rope. The wave's speed along the vertical rope will
1.remain constant up the rope. 2.increase with vertical position up the rope. 3.decrease with vertical position up the rope. 4.increase until midway up the rope, then decrease.
