Ammonia gas (A) and nitrogen gas (B) are diffusing in counterdiffusion through a straight glass tube 0.61m long at 298K and 101.32 kPa. The partial pressure of MH3is constant at 20.0kPa in one chamber and 6.666kPa in the other. If the diffusivity at 298K and 101.32kPa is 2.3*10^(-5)m^2/s

a)What is the flux of ammonia
b) Calculate the diffusion of ammonia if the diameter of the tube is 24.4mm.

Ammonia gas is diffusing at constant rate through a layer of stagnant air 1 mm thick....
Ammonia gas is diffusing at constant rate through a layer of stagnant air 1 mm thick. Conditions are fixed so that the gas contains 50% by volume of ammonia at one boundary of the stagnant layer. The ammonia at the other boundary is quickly absorbed and the concentration is zero. The temperature is 295 K and the pressure is 1 atm. If the diffusivity of ammonia in air is 0.18 cm2/s calculate the rate of diffusion of ammonia through the...

Nitrogen gas reacts with hydrogen gas to form ammonia gas . You have nitrogen and hydrogen gases in a -L container fitted with a movable piston (the piston allows the container volume to change so as to keep the pressure constant inside the container). Initially the partial pressure of each reactant gas is atm. Assume the temperature is constant and that the reaction goes to completion. Calculate the partial pressure of ammonia in the container after the reaction has reached...

CHEMICAL ENGINEERING Two bulbs are connected by a straight tube, 0.001 m in diameter and 0.15 m in length. Initially the bulb at end 1 contains N2 and the bulb at end 2 contains H2. The pressure and temperature are maintained constant at 25°C and 1 atm. At a certain time after allowing diffusion to occur between the two bulbs, the nitrogen content of the gas at end 1 of the tube is 80 mol% and at end 2 is...

A gas of CH 4 and He is contained in a tube at 101.32 kPa pressure and 298 K. At one point the partial pressure of methane is p A1 = 60.79 kPa, and at the point 0.02 m distance away, p A2 = 20.26 kPa. If the total pressure is constant throughout the tube, calculate the flux of CH 4 (methane) at steady state for equimolar counterdiffusion

Combustion gases passing through a 2.3-cm-internal diameter circular tube are used to vaporize waste water at atmospheric pressure. Hot gases enter the tube at 115 kPa and 250°C at a mean velocity of 5 m/s, and leave at 150°C. If the average heat transfer coefficient is 120 W/m2 °C and the inner surface temperature of the tube is 112°C, determine the tube length. Answer in cm with two(2) decimal places.

Water flows at 20 cm3/sec through a long straight tube that has an inner diameter of 1 cm. As the water flows, a toxin leaches from the tube into the water. At the inner surface of the tube, the toxin attains its saturation concentration, Csat = 2 mM. Fortunately, upon entering the water the toxin also irreversibly degrades into a non-toxic compound; this degradation follows first-order kinetics. Toxin Diffusivity D = 10-5 cm2/sec Toxin mass transfer coefficient k = 1.38...

Gas with a thermal conductivity of k = 0.04 W/mk and prandtl number of 0.7 is flowing at anaverage velocity of 0.5 m/s through a 2 mm diameter tube at a Reynolds number of 50. The heat capacity rate for the gas flowing through the tube is 0.001 kJ/s. The inlet temperature of the gas is 20C. There is a constant heat flux of 200 W/m^2 transferred from the tube wall into the gas. a) What is the Nu at...

Suppose we have two chambers in which NH3 gas is stored. In one chamber the concentration is held constant at (5.40x10^1) mg/m3, in the other it is constant at (1.3428x10^1) mg/m3. The two chambers are connected by a duct which is (2.269x10^0) meters long, (1.213x10^0) m wide and (3.4610x10^0) m high. If the diffusion coefficient of NH3 is (1.800x10^-2) m²/s, what is the amount of NH3 which is transported through the duct in kg/s ?

A gas mixture containing 80 mole% nitrogen and the balance n-hexane flows through a pipe at a rate of 90 m3/h. The gauge pressure is 1 atm and the temperature is 95 oC. a) Is the gas saturated or superheated? Find its degrees of superheat assuming this operation runs at constant pressure. b) To what temperature would the gas have to be cooled at constant pressure in order to condense 80% of the hexane?

Nitrogen gas at 60 kPa and 78C enters an adiabatic diffuser steadily with a velocity of 275 m/s and leaves at 85 kPa and 278C. Determine (a) the exit velocity of the nitrogen and (b) the ratio of the inlet to exit area A1/A2. Reconsider Using EES (or other) software, investigate the effect of the inlet veloc- ity on the exit velocity and the ratio of the inlet-to-exit area. Let the inlet velocity vary from 210 to 350 m/s.
