8. We observe that kerosene rises up
in the wick of a lantern. Take a
wick and put a spot of ink at one
of its ends. Then dip the wick in
kerosene just as you had dipped
the chalk in water in the
chromatography activity. Will
your experiment be successful in
seperating the colour ink spot. Try
it.​

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
