Problem 5.55

The measured volumetric flow rate of ethane at 10.0 atm absolute and 35C is 1.00 X 103 Llh. Using an estimated value of the second virial coefficient in the truncated virial equation (Equation 5.3-4), (a) calculate V(Llmol); (b) estimate the compressibility factor, Z; and (c) determine the mass flow rate of ethane in kg/h.

Step by step solution

Step 1 of 4

a)

Truncated virial equation for the non - ideal gases is as follows.

................................(1)

B = Virial coefficient

P = critical pressure

T = Critical temperature

R = Gas constant

To rephrase the equation (1) is as follows.

................................(2)

From table B.1 for ethane;

Critical temperature = = 305.4 K

Critical pressure = = 48.2 atm.

= 0.098
