Formaldehyde (CH2O) is made by the catalytic oxidation of pure methanol vapor and air in a reactor. The product stream from this reactor contains: 63.70 moles N2, 13.40 moles O2, 5.30 moles H2O, 4.10 moles CH2O, 12.30 moles CH3OH and 1.20 moles HCOOH. The reaction is 2CH3OH + O2 A side reaction occurring is 2CH2O + O2 2CH2O + 2H2O 2HCOOH

Steel is coated with a thin layer of ceramic to protect against corrosion. what do you expect to happen to the coating when the temperature of the steel is increased significantly? explain.

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
