We wish to strip so2 from water using pure air at the inlet at 20oc. the outlet water contains 0.0001 mole fraction so2, while the inlet water contains 0.0011 mole fraction so2. the column is operating at 1.125 atm, and l/v = 0.9 (l/v)max. assume hol = 2.76 ft and that the henry's law constant for so2 is 29.6 atm/mol fraction. calculate the packing height.

The higher the astm grain-size number, the coarser the grain is. a)-true b)-false

Which of the following ziegler nichols tuning methods the response of the controller to a step input should exhibit an s-shaped curve? a)-open loop mode b)-closed loop mode c)-both modes (open & closed) d)-none of the modes (open & closed)

Ahot wire operates at a temperature of 200°c while the air temperature is 20°c. the hot wire element is a tungsten wire of 5 um diameter and 2 mm in length. plot using excel current, heat transfer and heat generated by the wire for air velocity varying from 1-10 m/s in steps of lm/s? matlab the sensor voltage output, resistance, or assume nu 0.989 re033pr13 take air properties at tr (200°c20°c)/2 = 110°c properties of tungsten: c 0.13 kj/kg. k 3 p 19250 kg/m k (thermal conductivity) = 174 w/m. k
