3. Two boxes contain 4 balls each numbered from 1 to 4. An experiment consists in selecting randomly one ball from each box. Given that the sum of the 2 numbers coming up is greater than 6, the probability that the sum of the numbers is even is equal to

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

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

Calculate the bore of a cylinder that has a stroke of 18 inches and an extension time of 6 seconds at a flow rate of 4 gal/min.
