Solution outline for Problem 3.3(a,b)
In both palts, I expressed densities in kg/L which are numerically the same as g/cm3 thus they are
numerically the same as the specic gravity from the appendix.
This is because 1 kg = 1000 g and l L = 1000 cm3, and th

Solution outline for Problem 2.45
Start by rewriting equation as P = C/Vk or P = CVk. Use a loglog plot with the power law.
Excel plot and power law trend line are shown.
Answer: k = 1.573, C = 3.40x105 mmHg.cm4.719 or mmHg.(cm3)1.573
