Learning undergraduate engineering thermodynamics might be less painful with a blog. I hope that students, faculty and interested observers will share their thoughts on the laws of thermodynamics, phase and chemical equilibrium and many related topics.

HW #3 - P5 - Using Vapor Pressure Data to Estimate ΔHvap
Using the Clapeyron equation, estimate the enthalpy of vaporization of steam at 300 kPa, and compare it to the tabulated value.
Estimate dP*/dT using data from NIST. Your answers will not match those given in the HW. The author from which I took this problem used +/- 25 kPA to estimate the derivative. That is NOT a good idea. Use something like +/- 0.5 kPa or +/- 1 kPa and you r answer will be more accurate than the one I got from the other author.
