Problem 6

A container has a volume of 500 cm³ and is full of pure water at 180°F and 6000

psia.

a) How much water would be expelled if the pressure was reduced to 1000 psia?

b) What would be the volume of water expelled if the salinity was 20,000 ppm and

there was no gas in the solution?

c)

Rework part (b) assuming that the water is initially saturated with gas and that

all the gas is evolved during the pressure change.

d) Estimate the viscosity of the water.
