A sample stream of dry gas is being withdrawn from a stack. The stack gases are at 200 °C and 730 mm Hg. The rate of flow is determined to be 30.0 liters/minute at 20 °C and 790 mm Hg. Calculate the actual volumetric flow rate through the filter (at T= 200 °C and P= 730 mm Hg). If 1.42 mg of solid particles are collected on the filter in 30 minutes, calculate the concentration of particles in the stack gas (in ug/m³).

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.
