Toluene is fed to the first column at 1020 mol/hr while 74.4% of the benzene fed to the first column ends up in the overhead product. The overhead product of the first column contains only benzene and toluene. Benzene (B), toluene (T), and xylene (X) are fed to the first distillation column. A pair of distillation columns are being monitored by Beatrix and Enrico. m3, EEx: 284 kg/s= m3,p = Ex: 74.3kg/s m3, B =Ex: 15.7kg/sĢ.17.7: Two distillation columns with three components. Stream numbering is same as PFD for question 1. The composition of the overhead product stream is 91.5 mass % E and the balance P.įind the component mass flow rates (kg/s) exiting in the overhead product of the first distillation column. The overhead product from the second column contains 92.1% of the E inthe feed to this column. The overhead product of the first column is used as the feed stream to the second column. The bottom product stream of the first column contains 93.1 mass % B and no E, and 95.1% of the B in the feed stream is recovered in the bottom product stream. A liquid mixture enters the first column at 536 kg/s and contains 35.0 mass % ethanol (C₂H5OH), 15.0 mass % propanol (C3 H7 OH), and the balance butanol (C4 H9 OH). Two distillation columns, which are overseen by engineers Gianna and Peter, separate three components.

Since the original population has a normal distribution, the distribution of sample means is a normal distribution for any sample size.Ģ.17.6: Two distillation columns with ethanol, butanol, and propanol. Since the distribution is of individuals, not sample means, the distribution is a normal distribution for any sample size. Since the distribution is of sample means, not individuals, the distribution is a normal distribution for any sample size. Since the mean pulse rate exceeds 30, the distribution of sample means is a normal distribution for any sample size. Why can the normal distribution be used in part (b), even though the sample size does not exceed 30? O B. If 25 adult females are randomly selected, find the probability that they have pulse rates with a mean less than 79 beats per minute. If 1 adult female is randomly selected, find the probability that her pulse rate is less than 79 beats per minute. The following chart is data over an 8 month period that shows how much a company spent in advertising and the sales revenue for that month a)What is the correlation coefficient? (round to 2 decimals) b) Is it a positive or negative correlation? c) Would you say it is a strong correlation, weak correlation or no correlation?What is the indicator that lead you to that conclusion? d) What is the linear equation (y = mx + b form) that best approximates the relationship between advertising dollars spent(x) and sales revenue(y) based on the above 8 months of data? (round to 2 decimals for the slope and the y intercept) e) What sales revenue would the company expect for the following advertising spending? Round to nearest cent a) 3000 b) 2100 c) 1300 f) If you were in charge of the advertising department how much would you spend on each of the next 4 months on advertising and how and why did you arrive at your decision? Nov Jan Feb March Please give a short explanation as to how and why you came up with your advertising spending for the above 4 months.Īssume that females have pulse rates that are normally distributed with a mean of u=73.0 beats per minute and a standard deviation of o = 12.5 beats per minute.

Here is a list of some tools you may be interested in: If you're dealing with organic molecules, these codes will work far better than if you're dealing with inorganic complexes. They all work differently, and none are perfect at what they do. There are actually quite a number of tools that can be used to passivate a structure.
