A stream of air (contains oxygen and nitrogen) flowing at a rate of 10.0 kg/h is to be mixed with a stream of COz inside a mixer. The CO, enters the mixer at a rate of 20.0 m/h at 150 °C and 1.5 bar. What is the mole percent of CO; in the product stream?

A stream of humid air containing 10 mass % water enters a condenser where 85% of the water vapor in the air is condensed. The flow rate of the condensate is meausred and is 200 L/hr. Dry air may be taken as 21 mole% and nitrogen is 79 mole%. Find the flow rate of the gas stream (wet air) entering the condenser in kg/hr.

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.

The table below shows the flue gas composition (in gmol) from the combustion of fuel oil: 0₂ N₂ CO2 H₂O 0.092 2.054 0.421 0.576 Determine the wet and dry analysis of the products of combustion.
