Determine Z and V for steam at 250 C and 1800 kPa by the following.

a. The truncated viral equation Z=PV/RT=1+B/V+C/V^2 where B=-152.5 cm3/mol and C=-5800 cm6/mol2

b. the truncated viral equation Z=PV/RT=1+BP/RT with a value of B from the generalized Pitzer equation.

Looks great! Nice to see you putting in units.
I always emphasize this with my students.

cpinder · Answer

@surry99 thank you! I always put units because if I don't, I don't see what cancels.

Fantastic...that is exactly what you should be doing.
