Hot Soap is chilled on a roller and scraped continuously from the roller onto a moving conveyor belt which carries the soap into a dryer (see the figure below). The entering soap contains 25% water by weight. It is desired to reduce the water content to 15% by weight and produce 1200 lb/hr of nearly dry soap chips. The entering air contains 0.3 mole % water vapour. The dryer manufacturer suggests that the dryer operates efficiently when the nearly dry air/wet soap flow ratio is 3.0/ Calculate the unknown flow rates and compositions. Air is 21% Oxygen and 79% Nitrogen (mole basis) and has a molecular weight of 29.0 g/mol.

Principal Quantities and EOS

A physical quantity represents the physical state of a system. It is expressed as the product of a number and unit. The basic quantities used in science are length, mass, and time. The principal quantities are the quantities that are independent of other quantities.
