1.) A gas stream that contains 2.25 mole% CO2 flows through a pipeline. 45.0 kg of CO2/min is injected into the line. A sample of the gas is drawn from a point in the line 350 m downstream of the injection point and found to contain 3.0 mol% CO2. (a) Calculate the gas flow rate (kmol/min) upstream of the injection point (after steady state has been reached). (b) Calculate the mass of upstream and downstream, also the components.

Question
Solve the following problem. (Get the OMB, CB and draw the diagram) 1.) A gas stream that contains 2.25 mole% C02 flows through a pipeline. 45.0 kg of CO2/min is injected into the line. A sample of the gas is drawn from a point in the line 350 m downstream of the injection point and found to contain 3.0 mol% CO2. (a) Calculate the gas flow rate (kmol/min) upstream of the injection point (after steady state has been reached). (b) Calculate the mass of upstream and downstream, also the components. 2. For carrying out nitration reaction, it is desired to have a mixed acid containing 29% HNO3 , 57% H2SO4 (mass). Nitric acid of 68.8% (mass) is readily available (azeotropic composition). Calculate the required strength of sulphuric acid to the above mixed. 3. A continuous single effect evaporator is to be fed with 2500 kg/hr. of solution having 3 wt% solute. the feed is at a temperature of 207 k. it is to be concentrated to a solution of 5 wt% solute. the evaporation operating at a pressure of 101.3 kpa in the vapor space. saturated steam is supplied at 173.3 kpa for heating. Calculate the weight of the vapor produced
