A slurry (e.g. a mixture of sand / water, where water is 65% of the mass of the mixture) is being fed into a dryer, which removes 85% of the water. Assuming that 5.0 kg of the slurry is fed to the dryer each minute, what is the total mass flow rate leaving the dryer, as well as the mass fractions of both sand and water in the slurry that leaves the dryer. (include a diagram in your final answer)

In the mixing device the slurry (mixture) of ice and water at temperature 0°C is mixed with water at temperature 20 C. The flow rate of the slurry (water + ice) is 2 kg/s and flow rate of the warm water is 4 kg/s. (a) Determine the mass flow rate of the ice, if the outlet temperature is 1°C and system is perfectly insulated. (b) Determine entropy generation rate in the perfectly insulated system. Specific heat of water is 4.19...

A liquid mixture containing 45.0 % benzene (B) and 55.0 % toluene (T) by mass is fed to a distillation column. A product stream leaving the top of the column (the overhead product) contains 95.0 mole % B, and a bottom product stream contains 8.0 % of the benzene fed to the column (meaning that 92% of the benzene leaves with the overhead product). the volumetric flow rate of the feed stream is 2000 L/h and the specific gravity of...

Q's d and e
Lactose powder is being dried at atmospheric pressure at a rate of 12.0 [kg/s in a continuous dryer. Lactose powder enters the dryer at 20 [C] and with 10% water content (by mass) and leaves at 35 (C) with 1% water. Air at 50.0*C(dry-bulb) and 22 [C] wet-bulb temperature is used for this drying process. The air exits the dryer saturated at 25 ["C). Assume that the specific heats of water and lactose powder are independent...

4- Certain solid substances, known as hydrated compounds, have well-defined molecular ratios of water to some other species. For example, calcium sulfate dihydrate (commonly known as gypsum, CaSO4 2H30), has 2 moles of water per mole of calcium sulfate; alternatively, it may be said that I mole of gypsum consists of 1 mole of calcium sulfate and 2 moles of water. The water in such substances is called water of hydration. In order to eliminate the discharge of sulfuric acid...

1. Saturated liquid H20 at 16 MPa is fed into the boiler of a variant of a Carnot cycle (but simplified Rankin cycle) where the working fluid is not an ideal gas. Saturated H20 vapor is fed into the turbine of the same turbine. The condenser of this turbine is operated at 8 kPa. The mass flowrate of the H20 in this cycle is 7.2x103 kg/min. Draw the path of this process on T-s diagram. Estimate the thermal efficiency...

A mixture containing 42% benzene and 58% toluene by mass is fed to a distillation column. A second mixture is also fed to the distillation column and has a composition of 65% toluene and 35% acetone by mass. The flowrates of the mixtures are 2500 kg h1 and 1500 kg h1 respectively. An overhead distillate exit stream of 800 kg h-1 containing 23% acetone and a bottom exit stream of 25% benzene are produced. Determine the bottom exit flowrate and...

Q2. Copper ores rich in ultra-soluble sulfate minerals are leached using water. Finely grounded solid copper ore with 1000 kg/h, contains 20% CuSO4 (copper sulfate) and 70 % insoluble solids (Feed, F). The rest 10 % is contaminants and ignore their existence in your calculations. (Take only copper sulfate (solute) and solid content of the Feed.) The leaching occurs in a two- stage, counter-current system using 3000 kg/h of water as pure solvent. The ratio of kg insoluble solid to...
