Flow rate equations of water in packed column carbon dioxide and water process (non-chemical)
The Re number, which defines the mass transfer coefficient (k), will include the mass flow rate of the water, that is, the Re number will be written in m, not v. Since there is Co2 gas at the outlet, the concentration of the exiting gas will be written in terms of partial pressure. Co2 concentration will be written in the inlet part in terms of partial pressure. From the number Sh, k will be defined and defined in Re.

Hot water flows thorough a parallel flow heat exchanger at a rate of 10 kg/min and is cooled by a cold water stream of flow rate 25 kg/min. The inlet temperatures of hot and cold water streams are 70 oC and 25 oC, respectively. The outlet temperature of the hot water is expected to be 50 oC. The individual convective heat transfer coefficient on both sides of the heat transfer area is 600 W/m2 .K. Take the specific heat for...

Water enters a 20-mm tube at 27°C with a flow rate of 450 kg/h. The rate of heat transfer from the tube wall to the fluid is given as q5'(W/m) - a x, where the coefficient a is 20 W/m2 and x (m) is the axial distance from the tube entrance. (a) Beginning with a properly defined differential control volume in the tube, derive an expression for the temperature distribution T m(x) of the water. Use this expression to determine...

Air flows over a solid slab of frozen carbon dioxide formed in dry ice with an exposed cross- sectional area of 1.0x109 m². The carbon dioxide sublimes into the 2.0 m/s flowing stream at a total of mass flux rate is 2.29x107 mol/s and partial pressure is 4.7410Pa. The air is at ambient conditions of 293 K and 1.01310% Pa pressure. At this ambient condition, the diffusivity of carbon dioxide in air is 1.5x10-6 m²/s. At ambient conditions (293 K...

(8 pts) Carbon dioxide in the atmosphere dissolves in water to establish an equilibrium that can increase the acidity of aqueous solutions in the environment. This equilibrium is CO2(g) = CO2 (aq), Kn= 3.1 x 10-2 at 25°C. Kh is called the Henry's law constant, which relates the solubility of the gas CO2 in the aqueous solution, [CO2), to the partial pressure of CO2 over the solution, p(CO2): [CO2] (M)= Kn · p(CO2) (atm) During the preceding decades, the atmospheric...
