The design team responsible for developing this product attempt to study the passage of raw corn through the machine. Because the corn popping chamber is not transparent, an alternate method is used as follows. Whilst operating at steady state using raw corn, an instantaneous change from raw corn to a blue dyed corn is made. Camera 1 and 2 record the time difference from when the dyed corn is introduced and leaves the machine. Camera 2 V=1 Litre Camera 1 1 liter/min, unpopped A time difference of 30 seconds is recorded. (i) V=30 Litre/min Provide a sketch of the interior of the reactor showing the state of the contents as it passes through. An approximation of the kinetics of corn popping can be made by the Arrhenius model. The heat setting used in (i) was 1200W. The designers make a change by increasing the heating to 2400W. A time difference of 5 seconds is now observed. ii) Provide a second sketch of the interior of the reactor showing the state of the contents as it passes through at this higher heat setting. Explain how a more compact product may be designed.

environment showing (b) Describe the mechanism of distillation operation in a chemical processing how McCabe -Thiele method can be used to determine the feed plate for a distillation column.

Estimate the cut diameter and overall collection efficiency of a cyclone given the particle size distribution containing algae. Particle size distribution and other pertinent data are given below.   Average particle size dp, μm 1 5 10 20 30 40 50 60 >60 Wt % 3 20 15 20 16 10 6 3 7 Other design parameters are: Gas viscosity = 0.02 Cp; Specific Gravity of the particle = 3.0; Inlet gas velocity of cyclone = 14.6 m/s Effective number of turns within cyclone = 5 Cyclone diameter = 2.44 m Cyclone inlet width = 0.61 m

2. A 1 L, 100 g (dry weight) sample is removed from a continuous crystallizer which is operated with a residence time of 1000 s. The following particle size distribution is obtained for the sample: i) Size range (um) Mass (g) 200- 300- 400 500 600-700- 800- 300 400 500 600 700 800 900 0- 100- 100 200 2.5 26.0 30.0 21.0 12.0 6.0 2.0 0.5 0.0 Microscopy based on the sieve fractions has found that a volumetric shape correction factor, ky, of 0.52, for the crystal population and the crystal density has been found to be 2000 kg/m³ Determine whether the MSMPR model describes the system. If it does so, then determine the growth and nucleation rates for this system; if it does not, suggest why reasons that may cause deviation of this CSTR type crystallizer from the MSMPR model.
