Using the Noyes-Whitney model, calculate the rate of dissolution (in mg/min) of theophylline particles with the following parameters: Cs = 7.5 µg/mL, S = 3.75 x 103 cm2, D = 1.75 x 10-8 cm2/s, h = 25µm and Cb = 0.13µg/mL
N:B:
Given ,S = 3.75 x 103 cm2 , D = 1.75 x 10-8 cm2/s , Cs = 7.5 µg/mL , h = 25µm and Cb = 0.13µg/mL
1ml = 1 cm3 ,1 µm = 10 -4 cm.

2. the iv is infusing cia gravity flow. calculate the rate in
mcgtt/min.
the book says the answer is 90 mcgtt/min but how do you get
that?
7. how many mL of iv fluid is the patient receiving in 24
hours? the book says the ans is 2,160 ml. the body weight is 140lb
which is 64kg. what would be the next step?
here
are the answers to all the questions & the other questions not

7. Smokers are known to have about 50% higher CL than nonsmokers for theophylline. If the average observed AUC after administration of 300 mg IV theophylline in nonsmokers is 100 mg.hr/L, what is the expected AUC in smokers after administration of the same 300 mg dose? Theophylline undergoes linear pharmacokinetics 2. After administration of a single 400 mg dose of a drug, a linear plot of the serum concentration-time prorile on a semi-log graph paper showed a y-intercept of 1mg/mL...

The order reads: 900mL NS IV 5 hr. Calculate the flow rate in millimeters per hour when the drop factor is 10 drops per milliliter. The rate ordered by the physician is 80 microdrops per minute. How many milliliters per hour will this patient receive? 1,000 mL of NS must infuse via IV over 8 hours. The drop factor is 20 gtt/mL. Find the flow rate in gtt/min. An infusion of 5% D/W begins with 300 mL in the IV...
Model I: The Dissolution of Magnesium Hydroxide in Water When solid Mg(OH)2 dissolves in water, the chemical reaction is: Mg(OH)2(s) Mg2+(aq) + 2OH-(aq) (1) Table I. These are the results after equilibrium has been established for the addition of solid Mg(OH)2(s) to water yielding a final volume of 10.0 L of solution. Total amount of Mg(OH)2 added Mg2+ concentration in the resulting solution at eq OH- concentration in the resulting solution at eq Mass of Mg(OH)2 that does not dissolve...
