- 7-31. In the air dryer illustrated in Figure 7.31, part of the effluent air stream is to be recycled in an effort to control the inlet humidity. The solids entering the dryer (Stream #3) contain 20 % water on a mass basis and the mass flow rate of the wet solids entering the dryer is 1000 lb/h. The dried solids (stream 4) are to contain a maximum of 5 % water on a mass basis. The partial pressure of water vapor in the fresh air entering the system (Stream #1) is equivalent to 10 mm Hg and the partial pressure in the air leaving the dryer (Stream #5) must not exceed 200 mm Hg. In this particular problem the flow rate of the recycle stream (stream #6) is to be regulated so that the partial pressure of water vapor in the air entering the dryer is equivalent to 50 mm Hg. For this condition, calculate the total molar flow rate of fresh air entering the system (Stream #1) and the total molar flow rate of the recycle stream (Stream #6).

In order to avoid breathing this harmful gas, closed areas should be adequately ventilated. There is no specific standard for the air exchange rate. However, a complete freshening of air every 2.5 minutes has been accepted by the industry as effective ventilation. A worker maintains a rectangular tank with a height of 10 ft and a 5 ft x 5 ft square bottom. Fresh air enters through a 6-inch diameter hose and exits through a 3-inch diameter port on the tank wall. The flow is assumed to be incompressible and steady. Determine, a) The exchange rate required (ft³/min) for this tank. b) The velocity of the air entering and exiting the tank at this exchange rate.arrow_forwardGallium is produced by the electrolysis of a solution made by dissolving gallium oxide in concentrated NaOH(aq).Calculate the amount of Ga(s) that can be deposited from a Ga(III)solution using a current of 0.460 A that flows for 40.0 min. mass: garrow_forward

- 10. A container is separated into two halves by a membrane. Your lab partner assistant, Thurmond, is supposed to place a MgCl2 solution on side 1 and a NaCl solution on side 2. He is then supposed to measure the rate of water movement across the membrane. Unfortunately, Thurmond is not very good about keeping complete lab notes and he has forgotten to write down some data and calculations. Using your knowledge of osmosis, complete the following table. Temperature is 15°C and the hydraulic conductivity for the membrane is 0.4 ml/atm sec.
