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

Afull journal bearing has a journal diameter of 27 mm, with a unilateral tolerance of -0.028 mm. the bushing bore has a diameter of 27.028 mm and a unilateral tolerance of 0.04 mm. the l/d ratio is 0.5. the load is 1.3 kn and the journal runs at 1200 rev/min. if the average viscosity is 50 mpa-s, find the minimum film thickness, the power loss, and the side flow for the minimum clearance assembly.

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature

Which of the following components of a pid controlled accumulates the error over time and responds to system error after the error has been accumulated? a)- proportional b)- derivative c)- integral d)- on/off.
