For the VOC stripping task of Exercise 6.26, the expert has suggested that we use a tower diameter of 0.80 m for which we can expect a pressure drop of 500 N/m2-m of packed height (0.612 in. H2O/ft). Verify the information from the expert by estimating:

(a) The fraction of flooding using the GPDC chart of Figure with Fp = 24 ft2/ft3.

(b) The pressure drop at flooding.

(c) The pressure drop at the operating conditions of Exercise 6.26 using the GPDC chart.

(d) The pressure drop at operating conditions using the correlation of Billet and Schultes by assuming that 2-in. plastic Flexiring packing has the same characteristics as 2-in. plastic Pallrings.
