...2/ A plant wishes to dry a certain type of fiberboard. To determine drying characteristic, a sample of 0.3 × 0.3 m with edges sealed was suspended from a balance and exposed to a current of hot dry air. Initial moisture content was 75%. The sheet lost weight at the rate of 1 104 Kg /s unit the moisture content fell to 60%. It was established that the equilibrium moisture content was 10 %.The dry mass of the sample was 0.90 Kg.All moisture contents were on wet basis .Determine the time for drying the sheets from 75% to 20% moisture under the same drying conditions.

A 5.00-ml. sample of blood was treated with trichloroacetic acid to precipitate proteins. Alter centrifugation, the resulting solution was brought to a pH of 3 and was cxtraccd with two 5-mL portions of methyl isobutyl ketone containing the organic lead complexing agent APCD. The extract was aspirated directly into an air-acetylene flame yielding an absorbance of 0.454 at 283.3 nm. Five-milliliter aliquots of standard solutions containing 0.240 and 0.475 ppm Pb were treated in the same way and yielded absorbancc of 0.412 and 0.642. Calculate the concentration Pb (ppm) in the sample assuming that Beer's law is followed.

Present your solution in a technical report format, explaining steps and providing details. 9.1. An ice crystal in the form of a thin hexagonal plate grows by diffusion in an environment saturated with respect to water at a temperature of -4°C and a pressure of 80 kPa. Determine the time required for it to grow to a diameter of 1 mm, starting from a mass of 10-8 g. Take the capacity (capacitance, C) to be that of the circumscribing disk. Assume that the mass and the diameter of the plate are related by m = 1.9 X 10-2D³, with mass in g and D in cm. Neglect ventilation effects. If diameter and fall speed are related by u = KD; where K = 520 s-1, determine the distance the crystal falls during the growth to 1mm diameter. The key equation (9.2) could be dm/dt = 4+CD(pv - pvr) but if one allows for latent heat release one needs equation 9.4, and lots of assorted values. Not clear how to interpret the last 2 lines on p160 but you should use ice parameters
