The paragraph following equation 5.48 should read:
In general, equation 5.22b is required to solve for the density 
. These equations should be used for a gas in which there is significant temperature difference between the inlet gas and the gas already in the control volume. The variable r can be used to estimate how close you think the process is to an isothermal or adiabatic process. A more sophisticated approach is to consider the actual heat transfer. [Ref. 5.13]. Notice that equation 5.46 simplifies to 5.30 if the inlet temperatures are approximately equal to the control volume temperature.

First paragraph, beginning with Solution (correction in bold)
The inside of a watermelon is basically water and so should have a specific heat about equal to that of water. Therefore, we will assume that the specific heat Cp is 4200 J/(kg° C) and the density is 1000 kg/m3. With free convection h will be about 10 W/(m2° C). Based upon the mass and density of the watermelon, the diameter of the watermelon is 0.20 m, and the surface area of the watermelon is approximately 0.12 m2.
The first thing to do is calculate the Biot number. The thermal conductivity of water is 0.6 W/(m° C), so
(6.41)
Although this Biot Number is above 0.1, we still want to use a single-lumped capacitance model just to get a good estimate of time.
