Problem.2
30000 kg/hr of pure ethyl alcohol at 2 psi is to be condensed by water from 85 degree F to 125 Degree F. A dirt factor of 0.004 should be provided. A pressure drop at 2 psi is allowable for the vapour and 10 psi for the water.
Calculate the required size of 1-2 horizontal condenser using 1 inch OD 14 BWG, tubes 16 ft long on 1 1/4 inch triangular pitch.
solution::
