EBIO/ECHM 100 – Homework #6 2015 Due Thursday October 8, 2015 1. Flow rates – in most bio- or chemical engineering problems, you will be working with flow rates rather than a singular amount of mass, moles or volume. When working with gases, a molar flow rate (mol/time) or a volumetric flow rate (volume/time) can be used in the ideal gas law. Consider a mixed gas consisting of 60% Hydrogen, 20% Nitrogen and 20% Carbon Monoxide (CO) which has a molar flow rate of 175 lbmol/min. The temperature is 200oF and pressure is 3 atm gauge. a. Calculate the individual molar flow rates of each component (mol/min) b. Calculate the total volumetric flow rate in ft3/min c. Determine the molar density of the mixed gas (mol/ft3) d. Determine the mass flow rate of the gas (g/min) e. Determine the mass fraction of hydrogen in the gas Read Section 6.5 of your textbook and/or watch the mini-lecture on statistics. That information will help you complete problems 2-4 In previous years, students in EBIO/ECHM 100 would test their ability to brew a repeatable batch of coffee. Let’s say you tried your best to brew three identical batches of coffee – you ground your own beans and measured exactly how many grounds you added to the pot. You took three samples from each batch and measured the absorbance. Representative data for the absorbance readings is given below. Batch 1 Batch 2 Batch 3 Measurement 1 0.343 0.374 0.327 Measurement 2 0.342 0.372 0.327 Measurement 3 0.371 0.375 0.328 2. For each batch of coffee (data in a vertical column), calculate the mean and standard deviation of the absorbance measurement of the three measurements taken from each batch (batch 1 has 3 absorbance measurements of .343, 0.342 and 0.371). Show at least one hand calculation on engineering paper, but you can do the rest in Excel if you wish, using the functions for average, =average(), and standard deviation, =stdev(). For example if you put data from batch 1 in column B, cells B2, B3 and B4 you could tell Excel to compute the average of those numbers by entering the equation =average(B2,B3,B4) in a neighboring cell. An alternate to way compute the average would be to type =(B2+B3+B4)/3. While you get the same answer with both methods, the second method become more cumbersome as your number of samples goes up. 3. Now, calculate the mean and standard deviation for the combination of all nine samples. 4. Why is the standard deviation calculated in #3 greater than those calculated in #2? Discuss this question in terms of experimental factors that could lead to scatter in your data (think back to the steps of making coffee and try to come up with at least 3 factors – these can address sample to sample variations or batch to batch variations). Staple the spreadsheet to the rest of your HW if using Excel. Adjust numbers so they report correct significant figures.
