ChE 330 Fall 2015 HW 4 Due: Sept 24 5.1
(i) This is a standard Rankine cycle problem using steam.
This is a refrigeration cycle problem using propane (use p-H chart for propane in Appendix). 5.15 This problem is a Claude liquefaction process for methane. (Use methane p-H chart in Appendix). 6.2 (a, c, f, h, i) Here you are asked to express various derivatives in terms of certain variables (P, V, T and their derivatives and absolute S).
You may use Eqn. 6.37 - 6.41 as needed, as well as various definitions and calculus rules. 6.8 Joule-Thomson coefficient µJT is an important measurable derivative and can be used to test the validity of equations of state.
Here you are asked to express µJT using the vDW equation and the ideal gas equation. 6.10 (h) You know for ideal gas CP - CV = R. Here you are given data for ?, aP and ?T and asked to compute CP - CV. First see page 244 where the book derives (CP - CV ) for a general fluid. You express the RHS of that equation in terms of the given data, then compute the answer.
A packed tower is designed to recover 98% CO2 from a gas mixture containing 10 % CO2 and 90 % air using water . A relation y = 14 x can be used for equilibrium conditions where y is kg CO2 / kg dry air and x is kg CO2 /kg water. The water to gas r..
Adsorption and Membrane Processes
One type of commercial smoke detector contains a minute amount of radioactive americium-241 (241Am), which decays by -particle production. The particles ionize molecules in the air,
The ship must unload 1000 metric tons within 5 hours to avoid demurrage charges. Estimate the power required by the pump. Take the pump efficiency as 70%. Physical properties of toluene: density 874 kg/m3, viscosity 0.62 mNm-2 s.
Determine the acceleration potential (in Volts) that must be applied to electrons so that in an electron diffraction experiment of {200} planes of silver, Ag, they will result in first order diffraction at 2?
What is annihilation in terms of nuclear processes? Also, what are transuranium elements and how are they synthesized? Scientists have estimated that the earth's crust was formed 4.3 billion years ago.
A horizontal steel pipe having inner and outer diameter as 150 and 180 mm respectively is lagged with 50 mm thickness of 85% magnesia insulation inside ,which has flue gas flowing at 260oc
How much transmit power is required (disregarding power losses at transmitter and receiver ends) for a maximum BER of 10-5, when using:a. Coherently detected BPSKb. By how much must transmit power be increased to maintain the maximum BER of 10-5 if t..
A Small reaction bomb fitted with a sensitive pressure-measuring device is flushed out andfilled with pure reactant A at 1atm. Pressure. The operation is carried out at 25oC,atemperature low enough that the reaction does not proceed to any appreci..
A recovery of 95% of particles greater than 100 μm is required. The minimum operating temperature will be 10 °C and the maximum 30 °C. Design a hydro cyclone system to handle 1200 liters/min of this slurry.
Devise a control system for this reactor, and draw up a preliminary piping and instrument diagram. The following points need to be considered:
The heat capacity of thereactants and products are 1.95 kJ/kg-K, the volumetric flow rate is 0.33 m3/hr, and the feedtemperature is 20oC. If the conversion is 95%, calculate (a) the reactor size and (b) the temperature of the reaction mixture, ift..
