An air stream containing benzene is treated by a pollution control system, consisting of a hood, ductwork, activated carbon adsorbers, fan, and exhaust stack. The air flow rate is 150 standard m3/min (T = 20 oC and P = 1 atm). The ductwork is operated at T = 30 oC and a static pressure of -2.5 kPa while the barometric pressure is 0.99 atm. The ductwork dimensions are 0.4 m × 0.8 m. Find

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.

Water at the rate of 1 kg/s is forced through a tube with a 2.5 cm inner diameter. the inlet water temperature is 15°c, and the outlet water temperature is 50°c. the tube wall temperature is 14°c higher than the local water temperature all along the length of the tube. what is the length of the tube?
