You are the project manager of a team that has been asked to complete the design of a chemical plant up to the stage of design selection. You have three engineers available (plus yourself) and the work must be completed in ten weeks. Develop a project plan and schedule of tasks for each engineer. Be sure to allow sufficient time for equipment sizing, costing, and optimization. What intermediate deliverables would you specify to ensure that the project stays on track?
Find the relationship between voltage across the membrane and the concentration of CaCl2 before equilibrium is reached.
Find the total core loss if the frequency is increased to 400 Hz.
Make a rough estimate of the cost of steam per ton, produced from a packaged boiler. 10,000 kg per hour of steam are required at 15 bar. Natural gas will be used as the fuel, calorific value 39 MJ/m3 (roughly 1 MMBtu/1000 scf). Take the boiler eff..
What are Denbigh reactions? Explain its specialcases.?Denbigh (1958) was the first to treatthe following rather general reaction schemeA1R3S-rA= k12CArR= k1CA - k34CRrS= k3CR24rT= k2CArU= k4CATUk12= k1+ k2k34= k3+ k4With CAo+ CRo+ CSo+ CTo+ CUo= C..
Determine the vessel dimensions if the vessel is vertically mounted. Evaluate the relief loads for the blocked outflow and external fire cases and hence determine the relief valve size.
You may assume the components and their mixtures to be in the ideal-gas state at the pressures and temperatures of this problem. Is this a reasonable assumption?
Design a vapor compression cycle using ammonia as the refrigerant that will be used to maintain the temperature of a stream at - 20 °C. The evaporator is air cooled and the ambient temperature may be assumed to be 25 °C. Assume a compressor effici..
Explain what is meant by the term Threshold Limit Values (TLVs). Describe briefly the different TLVs used by Industrial Hygienists. Outline the strengths and weaknesses of these occupational exposure limits and illustrate how they may best be u..
For a coil current I (dc), derive an expression for the force on the plunger.
Show a schematic diagram of the seven segment decoder/driver block (available in IC form).
explain how a supercritical flow changes to a subcritical flow. You may need to refer text books and web pages to answer this question.
Does the current through the battery increase, decrease, or remain the same? Justify your answer.
