Equations of State for Real Fluids
Example 2.1
For a liquid ‘A’ at 350K and 1 bar, k = 50x10
-6

-1
. To what pressure must water be compressed at 350 K to change its density by 0.5%? Assume that k is independent of P.
At
T
= constant (using expression for
κ
)
Now
P

=1.005
P

bar = 100bar
P

+
= 100 bar
Back
bar = 100bar
= 100 bar
