A previously calibrated rotameter is being used to measure a gas flow. The old calibration curve is a straight line described by the following equation: Q = 1.10RR - 0.50 where Q = flow, liters/minute %3D RR = rotameter reading, dimensionless The rotameter was calibrated using ethane (C,Hg) at 1.40 ntm and 60 °F. The gas presently being used is methane (CHA) at 1.10 atm and 100 "F.

Basic Chemical Calculations (Process and Variables)

A basic chemical calculation involves the application of the law of chemical proportions to various reactions and material and energy balance calculations on various chemical processes. Basic chemical calculation helps students analyze various chemical processes and develop problem-solving skills. The chemical manufacturing processes are divided into unit operations involving physical changes of material and unit processes involving the chemical transformation of materials. For instance, fluid flow, heat transfer, and mass transfer are unit operations, and oxidation, reduction, and pyrolysis are unit processes.
