A mass transfer tower operating at 1 atm and 300 K uses water, which enters free of ammonia at the top, to reduce the ammonia (NH3) concentration in air exhausted from a reactor. At one plane (W) in the tower, the concentrations of ammonia in the liquid phase and at the interface are 35.2 mol/m3 and 41.5 mol/m3 respectively. The individual gas mass transfer coefficient is 1.1 mol/(m2 s ), and 20% of the resistance to mass transfer is in the gas phase. At 300 K, the Henry’s constant is 150 atm and water density is 998 kg/m3 . .
A. Interfacial and bulk pressure of ammonia in the gas at plane W (PAi, PAG).
B. Individual gas and liquid mass transfer coefficients (kg, kL)
C. Overall gas and liquid mass transfer coefficients (Kg, KL)
D. Molar flux (NA)
Water at 40 °F flows through the coils of the heat exchanger as shown in Fig. P8.81 at a rate of 0.9 gal/min. Determine the pressure drop between the inlet and outlet of the
A possible explanation of the leaning of the Pisa tower is that the subsoil contains a compressible clay layer of variable thickness. On what side of the tower would that cl
The characteristics at both low speed (approximately 20 mph) and high speed (90 mph) are of interest. For a series of projected model tests, a wind tunnel that will accommod
Collar C moves along rod BA with a velocity of 3 m/s and an acceleration of .5 m/s^2 both directed from B towards A and measured relative to the the rod. At the same instant,
Determine, with the aid of dimensional analysis, how the frequency is related to these variables. If the mass of the cylinder were increased, would the frequency increase or
An inventor claims to have developed a Lenoir engine with an isentropic compression ratio of 8.00 to 1 that produces a combustion temperature of 1500.°C when the intake temp
A steel collar whose outside diameter = 3.000 in at room temperature is to be shrink fitted onto a steel shaft by heating it to an elevated temperature while the shaft remai
Design a compound, reverted, spur gear transmission which will give two shiftable ratios of +5: 1 forward and -3.5:1 reverse with diametral pitch of 6. Specify pitch diamete
