A binary mixture with components A and B is to be separated in a distillation column to obtain 95 mol%. A as the top product. The binary mixture has a con stant relative volatility AB = 2. The column feed is a a - saturated liquid containing 50 mol % of A. Under the usual simplifying assumptions such as constant molal overflow, negligible heat loss, ideal trays, the mini mum reflux ratio for this separation is (rounded off to one decimal place)
Two tanks are connected by a series of pipes as shown below. Tank 1 initially contains 150 grams of salt dissolved in 20 liters of water, while tank 2 contains 50 grams of salt dissolved in 10 liters of water. Beginning at time t = 0, pure water is pumped into tank 1 at a volumetric flow rate of 3 liters per minute. This causes brine to flow between the tanks, and to flow out of both tanks at the volumetric flow rates shown in the Fig. 2. Determine the salt concentration in each tank (C, and C2) at any time t>0.
A solution containing 100 lbm KNO 3/100 lbm H 2O at 80°C is fed to a cooling crystallizer operated at 25°C. Slurry from the crystallizer (KNO3 crystals suspended in saturated solution) is fed to a filter, where the crystals are separated from the solution. Use the solubility data in Figure 6.5-1 to determine the production rate of crystals (lbm/lbm feed) and the solid-to-liquid mass ratio (lbm crystals/lbm liquid) in the slurry leaving the crystallizer.
A mixture of methane and air is capable of being ignited only if the mole percent of methane is between 5% and 15%. A mixture containing 9.0 mole% methane in air flowing at a rate of 7:00 x 102 kg/h is to be diluted with pure air to reduce the methane concentration to the lower flammability limit. Calculate the required flow rate of air in mol/h and the percent by mass of oxygen in the product gas. (Note: Air may be taken to consist of 21 mole% O2 and 79% N2 and to have an average molecular weight of 29.0.)
A tank, containing 1520 liters of liquid, has a brine solution entering at a constant rate of 3 liters per minute. The well-stirred solution leaves the tank at the same rate. The concentration within the tank is monitored and found to be c(t) = e(-t/800)/80 kg/L. Determine the amount of salt initially present within the tank. Initial amount of salt = ? kg. Determine the inflow concentration cin(t), where cin(t) denotes the concentration of salt in the brine solution flowing into the tank. cin(t) = ? kg/L

23 ft^3 of air was drawn from a ventilation duct and measured by means of a dry gas meter. the meter's temperature averaged 60 F and the meter gage pressure was -1.9" H2O. Barometric pressure during the sampling was 752 mm Hg. Calculate the volume in standard cubic feet and in standard cubic meter (25C, atm) this is an ideal gas problem
Can you help me answer this problem, a container of Atrazine (500 g) is dumped into a river 2.3 km upstream of a municipal water intake pipe. Cross-sectional area of the river is 5.7 m2. Assume that the Atrazine is dumped as a point source. The river flow is 8.25m3/s and the longitudinal dispersion coefficient is 0.1 m2/s, what is the maximum concentration (in ppm) expected at the intake. How spread out (in the direction of flow) is the atrazine at the time the peak concentration occurs at the intake pipe? Assume 2 standard deviations on either side of the peak is a good estimate of spread. Thank you
A lake with a surface area of 525 acres was monitored over a period of time. During a one-month period the inflow was 30 cubic-feet/second (cfs), the outflow was 27 cfs, and a 1.5-in. seepage loss was measured. During the same month, the total precipitation was 4.25 in. Evaporation loss was estimated as 6.0 in. Estimate the storage change for this lake during the month.
