Consider the two bulbs problem: Two bulbs are connected by a tube that is 2mm in diameter and 10cm long. Bulb 1 contains argon, and bulb 2 contains xenon. The pressure and temperature are maintained at 1atm and 105C. The binary diffusivity is 0.180cm2/s. At time t=0, diffusion begins for argon and xenon between the two bulbs. Assume that the bulbs have a diameter of 15cm. Then answer the following questions: 1. (4 pts) determine: (a) the time at which the argon mole fraction in the left bulb is 0.6 (b) the time when the argon mole fraction in the right bulb is 0.3. Report these in hours. (2 pts) After 90 hours, determine the molar flux of both argon and xenon. Report these in mol/cm2s. (3 pts) After 90 hours, plot the argon and xenon velocities, and report the value of vargon and vxenon at z=L. (1 pts) After 90 hours, determine the molar-averaged velocity of the mixture at z=L. (3 pts) After 90 hours, plot the mass-averaged velocity of the mixture in the tube and report its value at z=L
