Problem 1. a) Calculate the second virial coefficient of water at 200 °C using only data from the steam tables.
b) Use the truncated virial equation along with the second virial coefficient calculated above to estimate the volume of water at 200 °C, 14 bar. How does this value compare with the volume obtained from the steam tables? Discuss this comparison.
Problem 2. 1000 kg of methane is to be stored in a tank at 25 °C, 75 bar.
What is the required volume of the tank? (Hint: Use the Pitzer equation with the Lee-Kesler values.)
