A solution containing 100 lbm KNO3/100 Ibm H2O at 80°C is fed to a cooling crystallizer operated at 25°C. Slurry from the crystallizer (KNO3crystals 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.

- Calculate the solubility at 25 °C of PbCO3 in pure water and in a 0.0100M Pb(NO3), solution. You'll find Ksp data in the ALEKS Data tab. Round both of your answers to 2 significant digits. 0 // solubility in pure water: x10 solubility in 0.0100 M Pb(NO3)2 0-/- solution: L X 09 00 X S ?arrow_forwardSea water containing 4 wt. % salt (NaCI) is passed through a reverse osmosis (RO) membrane filtration unit to produce a "fresh" water product containing 0.5 wt.6 NaCI and a concentrated brine waste stream. If there are 28 kg of fresh water recovered from every 100 kg of sea water, then determine the concentration of the brine waste stream. Type your answer in as a weight percentage rounded off to one decimal place, but do not include the 6 symbol.arrow_forwardA tank contains 400 liters of brine holding 100kg of salt in solution. Water containing 125g of salt per liter flows into the tank at the rate of 12 liters per minute, and the mixture, kept uniform by stirring, flows out at the same rate. Find the amount of salt at the end of 90 minutes.arrow_forward
- A circular lake of diameter 2.5m is receiving wastewater with a flow rate of 25 L/sec from a village has phosphorus concentration of 0.5 mg/L. The lake receives Phosphorus point source concentration of 0.8 g/sec. If the wastewater is completely mixed in the pond and removes phosphorus with a removal rate of 12 m/year, find the concentration of phosphorus (mg/L) in effluent water stream? Assume steady state. (Round-off to one decimal place).arrow_forwardA variation of the indicator-dilution method (see preceding problem) is used to measure total blood volume. A known amount of a tracer is injected into the bloodstream and disperses uniformly throughout the circulatory system. A blood sample is then withdrawn, the tracer concentration in the sample is measured, and the measured concentration [which equals (tracer injected)/(total blood volume) if no tracer is lost through blood vessel walls] is used to determine the total blood volume.In one such experiment, 0.60 cm3 of a solution containing 5.00 mg/L of a dye is injected into an artery of a grown man. About 10 minutes later, after the tracer has had time to distribute itself uniformly throughout the bloodstream, a blood sample is withdrawn and placed in the sample chamber of a spectrophotometer. A beam of light passes through the chamber, and the spectrophotometer measures the intensity of the transmitted beam and displays the value of the solution absorbance (a quantity that…arrow_forwardA liquid mixture containing 40.0% benzene (B) and 60% toluene (T) by mass to the distillation column. The upper product stream contains 90 mol% B, and the lower product stream contains 6% of the benzene fed into the column (meaning that 94% of the benzene is left with the upper product). The volumetric flow rate of the feed is 2500 1/ hr and the specific gravity of .the feed mixture is 0.870 A- Rate of mass accumulation B- Component balance equation .

- Human saliva contains the enzyme α-amylase which hydrolyzes polysaccharide acetal linkages. A soda cracker (containing starch) was carefully ground; the crumbs were distributed evenly between two test tubes. The first test tube contained only water, while the second contained a 1% solution of α-amylase. Both mixtures were heated to 35°C for 10 minutes and filtered. The filtrates were tested with iodine solution and Benedict’s solution. Use the following results to answer the questions below. Mixture Iodine test Benedict’s Test cracker in water dark blue blue cracker in water and α-amylase red red-orange precipitate a. Was the starch from the cracker/water mixture hydrolyzed? Was the starch from the cracker in the 1% α-amylase solution hydrolyzed? b. Which cracker contained reducing sugars?arrow_forwardTwo aqueous sulfuric acid solutions are available at a processing facility: 20.0 wt% H2SO4 (sg = 1.139) 60.0 wt% H2SO4 (sg = 1.498) It is desired to mix the two solutions such that the final product has a concentration of 4.00 M (sg-1.213). There is 100 kg of the 20% solution available. If all of this is to be used, calculate: The mass of 60% solution needed The mass and composition of the final productarrow_forwardA steady-state process to recover crystalline potassium chromate (K,CrOz) from an aqueous solution of this salt is required. Four thousand kilograms per hour of a solution that is one-third K,CrO, by mass is joined by a recycle stream containing 36.4% K2CrO7, and the combined stream is fed into an evaporator. The concentrated stream leaving the evaporator contains 49.4% K,CrO; this stream is fed into a crystallizer in which it is cooled (causing crystals of K,CrO, to come out of solution) and then filtered. The filter cake consists of K,CrO, crystals and a solution that contains 36.4% K,CrO, by mass; the crystals account for 95% of the total mass of the filter cake. The solution that passes through the filter, also 36.4% K,CrO,, is the recycle stream. 1- Draw the flowchart of the system and put all known information. 2- Calculate the rate of evaporation, the rate of production of crystalline K,CrO7, the feed rates that the evaporator and the crystallizer must be designed to handle, and…arrow_forward
- A brine solution of salt flows at a constant rate of 9 L/min into a large tank that initially held 100 L of brine solution in which was dissolved 0.4 kg of salt. The solution inside the tank is kept well stirred and flows out of the tank at the same rate. If the concentration of salt in the brine entering the tank is 0.04 kg/L, determine the mass of salt in the tank after t min. When will the concentration of salt in the tank reach 0.01 kg/L?
