Combustion gases contain CO2, CO, O2, N2 and water vapor. It is common practice to report the composition in volume % on a dry basis (water-free) called the ORSAT analysis and to indicate the water content by its partial pressure. A typical analysis is as follows: 12% CO2, 3% CO, 7%O2, 78%N2 with Pressure of water of 1.33 kPa at a total pressure of 101 kPa. What is the composition on a wet basis(inc1uding water).

Consider the following samples of gas.Select the set of graphs below that show the distributions of the speed of the atoms in each sample (please take a photo of the correct graph).

Determine the specific volume of refrigerant-134a at 2MPA and 100°C, using (a). the ideal-gas equation of state.---- (b). the Vander Waals EOS. (Calculate the Vander Waals EOS parameters using the equations and obtain the data values form the steam tables).Compare the values obtained to the experimentally determined value of 15,000 KPa.---- (c).Using the generalized compressibility chart. Determine the error involved in each case.----

A stream of liquid water at a rate of 8 lit/s with a stream of methanol and ethanol mixture (contains 25 mol% methanol) are fed to continues evaporator. Another stream of methanol at a molar flow rate of 1 that of the alcohol mixture stream is fed to the same unit. If the liquids are evaporated totally and the produced vapor stream contains (0.1*1) mol% of water at a pressure of 28 psi and 220 °F, calculate: 1- The flow rate and composition of all streams in a molar, mass, and volumetric basis 2- The average molecular mass of all streams The Specific gravity of methanol is 0.762 and that of ethanol is 0.789 while the density of vapors can be estimated as: p=p*Mw/R*T where R-0.082 atm.m'kmol.K.
