Question

Accepted Answer

Reynolds number is a dimensionless quantity used in fluid mechanics to predict flow patterns in different fluid flow situations.

Reynolds number is calculated as the ratio of inertial forces to viscous forces in a fluid flow.
It helps determine whether the flow is laminar, turbulent, or transitional.
Ideal gas law relates the pressure, volume, and temperature of an ideal gas.
Laws of thermodynamics include the first law (energy conservation), second law (entropy increase), and third law (absolute zero).
Co-current flow in a heat exchanger involves both hot and cold fluids flowing in the same direction, while countercurrent flow involves them flowing in opposite directions.
Unit operations are individual steps in a chemical process (e.g. distillation, filtration), while a process involves a series of unit operations to achieve a desired outcome.
