18. A continuous thickener is required to concentrate a slurry of calcium carbonate in water from a solids content of 50 kg/m³ to 130 kg/m³, and to produce a clear overflow containing no calcium carbonate. The density of the dry calcium carbonate is 2300 kg/m³. A single batch sedimentation test produced the experimental result below: Time, hr 0 1.0 2.0 3.0 4.0 5.0 6.0 7.0 8.0 9.0 10.0 2, m 1.1 0.98 0.82 0.68 0.54 0.42 0.35 0.31 0.28 0.27 0.27 If the thickener is fed with slurry at a rate of 0.06 m³/s, the minimum thickener area in square meter that is required is a. 1005 b. 505 c. 1505 d. none of these

In the development of an operating policy (campaign) for batch distillation, what is done with intermediate (slop) cuts?

What is the best method for estimating the distribution of nonkey components at the actual (operating) reflux?

What is the limitation of a single-section cascade?

L₂60 P=1 Q1/A cylindrical core sample has a length of 6 cm and a diameter of 1 inch. the sample is crashed and placed in a graduated cylinder it displaced the water by 15 cm³, calculate the absolute porosity.

reverse osmosis desalination Cartridge filters i need step by step please

thank you can do part C   Determine the fraction conversion occurring in the pond & the tank separately & determine the overall conversion of the process.

what goals would you set to become a chemical engineer

can youdo part d and e now

this is amazing, can you expand a litte more on how to create this in excel
