100 m3/min of a gas mixture containing 1 mol % water and 99 mol % air is cooled at constant pressure of 1 bar from 200 °C to 25 °C. 50 % of the water in the inlet stream is condensed during this process. Calculate the cooling duty of the process (kW)
The Soave-Redlich-Kwong equation is a commonly used cubic equation of state, second in popularity only to the Peng-Robinson Equation of state. In this problem, just derive the two equations (7.66) given in the problem.
Negligible heat is transferred from the nozzle to its surroundings. The approach velocity of the steam is negligible. The specific enthalpy of steam is 2974J/kg at 260°C and 7bar and 2860kJ/kg at 200°C and 4bar. Use the open-system energy balance ..
Calculate the flow rates of burets Y and Z. Assume the flow rates remain constant during the experiment.
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 var..
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 ------
Natural gas composed of 60. mol% methane, 30. mol% ethane, and 10. mol% propane at 25 °C and 500. psia is fed at a rate of 50. m3/hr into a boiler. In the boiler it is blended with enough air to provide 20% excess oxygen and combusted.
oleum or fuming sulfuric acid available commercially in concentrations ranging from 20 to 99.9 sulfur trioxide. a.
Two separate metal blocks of thickness d and 2d are kept at constant temperature T0 at the top anda constant heat flux q0 is provided at the bottom. Draw the steady state temperature profile for eachof the blocks.
Develop the designed circuit using breadboard in the laboratory. Available thermal sensor can be used in the circuit. Discuss the effect of resistors on calibration of the sensor with specific emphasis on the sensitivity of the instrument.
Two equilibrium stages at 25C are used as shown in the following diagram. If 300 kg H2O/h is fed to each extraction unit, what fraction of the acetone in the feed solution would be removed and what would be the composition of the combined extract?
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 pro..
