A pure liquid composed of species A is brought into contact with a stagnant gas which initially contains only species B Evaporation of the liquid begins at !=0, leading to a mixture of A and B in the gas; B is insoluble in the liquid and therefore remains in the gas phase. The liquid interface is maintained at z=0, and the gas occupies the space z>0. The mole fraction of Ain the gas at z=0 is X4g. The system is at constant temperature and pressure and the gas mixture is ideal, so that the total molar concentration in the gas is constant, (a) Show that the mole fraction of A in the gas, 1,(z 1), is govermed by DAS A(0. ) a - DAs a at X(z. 0) =0, La(e, 1) =0.

What is the best method for estimating the distribution of nonkey components at the actual (operating) reflux?

Diagrams need also for this. 2-Electrolyte: The intricate dance of electrons is aided by a liquid bridge filled with a redox mediator between the anode and counter electrode.

7.40. The cart in Fig. 7.38 has a mass of 2000 kg. It is resting on frictionless wheels on a solid, level surface and encounters no air resistance. At time zero it is standing still, and a jet from a fire hose is used to start it moving. The mass flow rate of the fluid from the fire hose is 100 kg / s, and its velocity relative to fixed coordinates is 50 m/s. The cup on the rear of the cart turns the jet around so that it leaves in the -x direction with the same velocity relative to the cart with which it entered. Calculate the velocity-time behavior of the cart; assume the jet is unaffected by gravity. (This is not a very practical problem, but it is analogous to the more complex and interesting problem of starting a large turbine from rest. All such turbines must be occasionally shut down for maintenance; their starting and stopping behavior is more complex than their behavior running at a steady speed.)
