4. A mixture of water and ethyl alcohol containing 0.16 mole fraction alcohol is continuously distilled in a plate fractionating column to give a product containing 0.77 mole fraction alcohol and a waste of 0.02 mole fraction alcohol. It is proposed to withdraw 25 per cent of the alcohol in the entering stream as a side stream containing 0.50 mole fraction of alcohol. Determine the number of theoretical plates required and the plate from which the side stream should be withdrawn if the feed is liquor at its boiling point and a reflux ratio of2 is used.

Question
Given below are performance curves for a centrifugal fan with D=914 mm and ω=600 rev/min, as measured on a test stand using air at ρ=1.20 kg/m³. Scale the data to predict the performance of a similar fan with D’=1070 mm, ω’=1150 rev/min, and ρ’=0.72 kg/m³. Estimate the delivery and power of the largest fan when it operates at a system pressure equivalent to 190 mm of H₂O. Check the specific speed of the fan at the new operating point.

Question
A mixture of acetone vapour and air containing 5% by volume of acetone is to be freed of its acetone content by scrubbing it with water in a packed bed absorber. The flow rate of the gas mixture is 700 m3/hr of acetone free air measured at NTP, and that of the water is 1500 kg/hr. The absorber operates at an average temperature of 20 °C, and a pressure of 101 kPa. The scrubber absorbs 98% of acetone. The equilibrium relationship for the acetone-vapour-water system is given by: Y (kmol acetone/kmol dry air) = 1.68X(kmol acetone/kmol water) Calculate the following: (0) (ii) [5] [5] Amount of acetone absorbed The mean driving force for absorption, mass transfer area if the overall mass transfer coefficient is Ky = 0.4 kmol of acetone/m2 hr (kmol acetone/kmol dry air).

Question
The frame assembly has a mass of 8000 kg and it is hoisted using the boom and pulley system shown in the picture. The boom has a mass of 2000 kg and a mass center at G. a) Determine the compressive force in the hydraulic cylinder needed to support the boom when the frame assembly is off the ground but the actual lifting hasn’t started yet. b) Lifting starts: the winch at B draws in the cable with an acceleration of 2 m/s 2 . Determine the compressive force of the cylinder now.
