Aglass melting furnace is burning ethene (c2h4) in pure oxygen (not air). the furnace operates at an equivalence ratio of 0.9 and consumes 30 kmol/hr of ethene. a. determine the energy input rate based on the lhv of the fuel. express your result in kw. b. determine the o2 consumption rate in kmol/hr and kg/s.

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.
