Consider the distillation of a hydrocarbon stream composed of 35 mol% isopentane, 35 mol% n-hexane, and 30 mol% n-heptane supplied as a two-phase mixture that is 40% vapor at 100 kmol/h. The vapor and liquid products coming out from the flash distillation are in equilibrium each other. The distillation operated at 1520 mmHg pressure and 111°C. Required:
Determine the vapor and liquids flow rates and compositions of the outlet.

Ajournal bearing has a journal diameter of 3.250 in with a unilateral tolerance of 20.003 in. the bushing bore has a diameter of 3.256 in and a unilateral tolerance of 0.004 in. the bushing is 2.8 in long and supports a 700-lbf load. the journal speed is 900 rev/min. find the minimum oil film thickness and the maximum film pressure for both sae 20 and sae 20w-30 lubricants, for the tightest assembly if the operating film temperature is 160°f. a computer code is appropriate for solving this problem.
