Polycarbonate, PC, is used for aircraft canopies. A batch of this polymer was found to fail prematurely when impacted by a 4 pound bird during qualification studies. You suspect that the problem is due to a molecular weight difference for this particular batch of polymer compared to previous batches. You decide to perform dilute solution viscosity studies to determine the Mol.wt. Assume density is 1.2g/cm3 What solvent would you use? Justify your answer Please answer very soon will give rating surely

It's possible that poor software project management was to blame for the failure of the baggage system at Denver International Airport. Is it feasible to illustrate the steps involved in project management using an example? How, exactly, is it possible for a system to be a scientific triumph but a business disaster for the organisation?
The interfacial energy γoil-water of an oil – water interface at 25 oC is 53 mJ/m2. The surface tension of the oil is 25 mN/m and that of water is 72.5 mN/m at 25 oC. (a) Calculate the spreading coefficient. Does the oil spread on water at 25 oC? (b) When carboxylic acid is dissolved in the oil, γoil-water is reduced. We may assume that acid addition only affects γoil-water, which decreases linearly with acid concentration (dilute solution). It is observed that spreading of the oil occurs when the acid concentration in greater than 0.005 mol/L. Calculate the adsorption isotherm Γ versus C for adsorption of acid at the interface, and the area occupied by each acid molecule at the interface at the onset of spreading.
A drug is infused continuously intravenously (IV) for treatment of a particular disease. The volume of the body fluid V = 16 liters. The drug is excreted (removed) through the kidneys at rate ke , proportional to the concentration of the drug in the body fluids. The drug is ineffective and not used by the body if its concentration is below Cmin and becomes poisonous if the concentration goes over Cmax . It is metabolized at a rate km as the concentration is >=Cmin. Let the parameter values Cmin= 4 mg/l, Cmax =40 mg/l, ke = 0.2/hr and km = 0.3/hr.a. How much is the maximum possible rate of infusion of the drug?b. How long the drug would continue to be effective if the infusion has been stopped as the concentration reached at the maximum level?

There's 1 drink (and you are asked to determine the glucose concentration in the drink in the units of g/100mL. (Why these units? Well, once you have the concentrations in g/100mL you will be able to compare your values with the nutritional values given on the drink bottles’ labels). The sample of the drink was diluted 1/100 (i.e. by a factor of 100). This was an essential step in the method because, without it, the machine used to analyse the glucose concentration (spectrophotometer) would have given an error as the concentration would have been too high for accurate detection. What this means for you is that the dilution factor will need to be taken into consideration in your calculations (remember the aim is to calculate the concentration in the original drink and not in the diluted drink). You measured the concentration of their diluted drink using the spectrophotometer and their results were provided to them in the units mM (millimolar). Glucose Concentration in mM of drink =…

It is estimated that the net amount of carbon dioxide fixed byphotosynthesis on the landmass of Earth is 5.5 x 1016 g/yrof CO2. Assume that all this carbon is converted into glucose.(a) Calculate the energy stored by photosynthesis onland per year, in kJ. (b) Calculate the average rate of conversionof solar energy into plant energy in megawatts, MW11W = 1 J/s2. A large nuclear power plant produces about103 MW. The energy of how many such nuclear power plantsis equivalent to the solar energy conversion?
