Design a small, laboratory-scale, reversed Brayton cycle air conditioning system that can serve as an experimental apparatus for a junior or senior mechanical engineering laboratory course. The system must be instrumented with the proper pressure, temperature, and mass flow transducers so that its coefficient of performance can be accurately determined.
The system should have at least one variable parameter to provide a range of performance to study. You may wish to start by modifying an automotive turbocharger to provide the turbine and compressor stages.
Either construct the apparatus yourself or else provide sufficiently accurate and detailed drawings and instructions that it can be made by an engineering technician.
What is the molarity of a phosphoric acid stock used to make 750ml of a dilute 4M solution if 52ml of the stock was used?
Which is the limiting reagent in the reaction between Copper sulfate pentahydrate and ammonia?
What is the pH at the stoichiometric point? What is the pH when 105% of the base required to reach the stoichiometric point has been added?
which portion of the titration curve are you in to reach pH = 7? Show your calculations to prove that dilution of 10,000 gal aniline requires 0.58 gal of this acid.
Explain why the boiling point of your cyclohexane: toluene mixture rose slowly throughout your simple distillation procedure. Explain this in terms of the temerature/composition diagram
