In the commercial production of sugar (sucrose), the product crystals are washed and centrifuged to partial dryness. the crystals are then sent through a rotary dryer where they are contacted with a hot stream of air that reduces the moisture content from 1: 0 wt% to 0: 1 wt%. the ratio of wet sugar to inlet air fed to the dryer is 3.3 kg wet sugar/kg inlet air. the inlet air contains 1.5 mole% water. (a) draw and label the flowchart and do the degree-of-freedom analysis

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10

Air is compressed isentropically from an initial state of 300 k and 101 kpa to a final temperature of 1000 k. determine the final pressure using the following approaches: (a) approximate analysis (using properties at the average temperature) (b) exact analysis
