Answer 1

Answer #1

volumetric flow rate of C2H6O2 = 55.0 ft3/min

Density of C2H6O2 = specific gravity x density of water

= 1.113 x 62.3

= 69.3399 lbm/ft3

Mass flow rate = density x volumetric flow rate

= 69.3399 lbm/ft3 x 55.0 ft3/min

= 3813.6945 lbm/min

Molar flow rate = mass flow rate / molecular weight

= (3813.6945 lbm/min) / (62.07 lbm/lbmol)

= 61.44 lbmole/min
