A packed tower is to be used to remove 90% of the ammonia from an air stream containing of 5% of ammonia by volume. The feed gas rate is 100 lb mol/hr at 20 °C and 1 atm. Water at 90 lb mol/hr containing no ammonia is used as a solvent and the packing is 1-inch Raschig rings. Assume the tower is isothermal at 20 °C. It is to operate a 60% of flooding. In addition, for this system m...

L 2. Steady statemass balance: Water is flowing at steady state in a 0.1 meter-diameter pipe with a maximum velocity (turbulent profile) of 0.3 meters/sec. The pipe then goes through an expansion, to where it is then flowing in a 0.5 meter-diameter pipe, and the flow regime has changed from turbulent to laminar. In the second section of pipe, calculate the velocity as (a) block flow profile (Vavg), and (b) maximum velocity in laminar flow profile? HINT: you will need...
Water at 10°C (p = 999.7 kg/m3 and μ = 1.307 × 10-3 kg/m.s) is flowing steadily in a 0.20-cm-diameter, 15-m-long pipe at an average velocity of 1.2 m/s
8-31 Water at 10°C (p = 999.7 kg/m3 and μ = 1.307 × 10-3 kg/m.s) is flowing steadily in a 0.20-cm-diameter, 15-m-long pipe at an average velocity of 1.2 m/s. Determine (a) the pressure drop, (b) the head loss, and (c) the pumping power requirement to overcome this pressure drop.

2 A paint sprayer pumps air through a constriction in a 0.025- m diameter pipe, as shown in the figure. The flow causes the pressure in the constricted area to drop and paint rises up the feed tube and enters the air stream. The speed of the air stream in the 0.025-m diameter sections is 5.00 m/s. The density of the air is 1.29 kg/m3, and the density of the paint is 1200 kg/m3. We can treat the...
