1) A self-employed chemical engineer is on contract with Dow Chemical, currently working in a relatively high-inflation country. She wishes to calculate a project's PW with estimated costs of $35,000 now and $7000 per year for 5 years beginning 1 year from now with increases of 10 % per year thereafter for the next 8 years. Use a real interest rate of 12% per year to make the calculations.
A black body of finite dimension at 1000K is inserted into an infinite medium at 300 K. Given Stefan Boltzman constant as 1.8*10-5 W/m2K4, the radiative heat transfer coefficient is ------
Discuss the applicability of each model - Does it differ based on the interactions you would expect for each model. Can you conclude that one of the models is 'better' than the others from your graphs/analysis in Problems 3.1-2?
Determine the SO2 concentration in the exiting gas as a function of solvent flow rate from 25 to 175 mol/min and prepare a graph for our staff to use in operating this process
Develop a mathematical model (differential and algebraic equations) that describes the exit temperature if heat losses to the ambient occur and if the ambient temperature (Ta) and the incoming stream's temperature (Ti) both can vary

The final temperature of the uranium and deuterium oxide mixture is 28.5C. Given the densities of uranium (19.05 g/cm3) and deuterium oxide (1.11 g/mL), what is the edge length of the cube of uranium?
Select suitable valve types for the following applications: a. Isolating a heat exchanger. b. Manual control of the water flow into a tank used for making up batches of sodium hydroxide solution.
Using the data given in Appendix C (available online at booksite .Elsevier.com/Towler), calculate the gross and net calorific values of the gas. Give your answer in MJ/m3, at standard temperature and pressure.
Principles associated with the theory of Creep and Viscoplasticity need to be identified and your understanding of these principles. Graphs, tables, calculation etc should be included for better illustration.
Preliminary design work has been done on a process to recover a valuable product froman effluent gas stream. The gas will be scrubbed with a solvent in a packed column;the recovered product and solvent separated by distillation; and the solvent co..
