(c) An inlet water solution of 100 kg/h containing 0.010 wi fraction nicotine (A) in water is stripped with a kerosene strean of 200 kg/h contuining (0.0005 wt fraction nicotine in a countercurrent stage tower. The water and kerosene are essentially immiseible in cach other. It is desired to reduce the concentration of the exit water to 0.0010 wt finction nicotine. Given the equilibrium data below, with x the weight fraction of nicotine in the water solution and y in the kerosene. y y 0.001010 0.000806 0.00746 0.00682 0.00246 0.001959 0.00988 0.00904 0.500 0.00454 0.0202 0.0185 Using analytical method and Mc Cabe -Thiele method, determine the number of stages required to carry out the extraction
