A methanol-water solution is in contact with an organic solvent at one surface. Please answer the following questions: Diffusion will take place. Which species will transfer in the system (i.e., which molecule would you call "A")? • Is this diffusion in liquids, gases, or solids? Explain why Is it equimolar counter-diffusion or diffusion of A through stagnant non-diffusing B? Why? Draw a schematic of the system and indicate the direction of flux and the thin film through which you can calculate flux of A.

Please answer the following: a) Write the equation you would use to determine flux using the liquid film data. b) Write the equation you would use to calculate the mass transfer coefficient needed to determine flux in part a. c) Do you have all the data needed to calculate the driving force for H2S to transfer through the liquid film? If you do not have all the data, which parameters are unknown? Flowing H₂O PAI XA2 PA2 Bulk gas (composed of air + H2S) Thin film

Μ 60 ft Part A A man having a weight of 180 lb sits in a chair of the Ferris wheel, which has a weight of 15,000 lb and a radius of gyration of k = 37 ft. If a torque of M = 80(103) lb-ft is applied about O, determine the angular velocity of the wheel after it has rotated 180°. Neglect the weight of the chairs and note that the man remains in an upright position as the wheel rotates. The wheel starts from rest in the position shown. w= 0.888 rad/s w= 0.836 rad/s w= 0.849 rad/s w= 0.874 rad/s Submit Request Answer Provide Feedback 15,000 lb 80(10) Ib Oy Ox 60 ft 180 lb Next >
