A vertical vessel a nominal capacity of 5000 gal. is to be mounted on four electronics shear-type load cells. the system is designed so that in extreme case, three of the four loads cell can carry the entire weight. The liquid specific gravity is 1.15. The tare weight of the empty vessel is 5380. shear type load cell are available in the following range 2000lb, 5000lb, 20,000lb, and 30,000lg 1- select a measurement range from the weight system. 2-The electronic load cell readout has four active digits to display the weight. what is the smallest weight that can be display. 3-given a accuracy of 0.1% what is the maximum inaccuracy in lb when the tank is full? 4- given an accuracy of 0.1% what is the maximum inaccuracy in lb wen the tank is 10% full?

What are the main chemical reactions involved in AMD formation?
What is the “initiator reaction” and the “propagation cycle”?
Why is this cyclical nature (regeneration of Fe2+) problematic? How do microbes play a role in these reactions?
What is “yellow boy”? Oxidation of Fe2+ is very slow at low pH values. Why does this reaction occur then in acidic environments?

For cell culture, various laboratories use different volumes of culture medium in their culture flasks according to their conventions. However, many do not consider how this might affect the diffusion time of O2 from the gas/liquid interface to the cells attached to the bottom of the flask. To address this, it is useful to have an understanding of how the O2 diffusion time might be influences by the volume of medium added. A typical cell culture flask has a surface area available for cell attachment of 75 cm2 , therefore the height of medium, thus the diffusion distance will be a function of the volume of culture medium added. Cell culture is typically done at a temperature of 37 ºC. a) Calculate the diffusion time for O2 through culture medium from the gas/liquid interface if the height of medium (distance from the gas/liquid interface to the bottom of the culture dish) is 4 mm. Use the Einstein's approximation equation to determine your answer and cite the reference for the O2 diffusivity value you used in your calculations. b) Produce a plot of the O2 diffusion time as a function of culture medium volume for volumes in the range of 7 to 15 ml. c) If you wanted to standardize your laboratory’s practice in cell culture by keeping the height of culture medium the same (at 1.2 mm) for whatever vessels you use to culture cells, what volumes would be required for: - Standard round cell culture dishes with 35, 60, and 100 mm diameter. - For flasks, standard surface areas are 25, 75, and 175 cm2 . Show calculations for one of the conditions and present your results for all of the conditions in a table

(a) Derive Freundlich and Langmuir isotherm equations.
(b) An aqueous solution containing a valuable solute is colored by a small amount of an impurity. Before crystallization, the impurity is to be removed by adsorption on a decoloring carbon which adsorps only insignificant amount of the principal solute. Equilibrium data at constant temperature is as follows:
Kg C/Kg Solution | 0 | 0.001 | 0.004 | 0.008 | 0.02 | 0.04 |
Equilibirum Color/Kg Solution | 9.6 | 8.6 | 6.3 | 4.3 | 1.7 | 0.7 |
It is desired to reduce the color intensity to 10% of its
original value (9.6)
(1) Find out Freundlich adsorption isotherm
(2) Determine the quantity of fresh carbon requirement per 100 kg
of solution for a single stage operation.
