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.)
The curie (Ci) is a commonly used unit for measuring nuclear radioactivity: 1 curie of radiation is equal to decay events per second (the number of decay events from 1 g of radium in 1 s).
