Steady State Flow Fluids

Steady-state flow refers to the condition where the fluid properties at any single point in the system do not change over time. These fluid properties include temperature, pressure, and velocity. One of the most significant properties that is constant in a steady-state flow system is the system mass flow rate. This means that there is no accumulation of mass within any component in the system.

For example, in a steady-state flow of a gas in a pipeline, pressure loss occurs due to friction between the pipe wall and the flowing gas. The general flow equation can be used to calculate the pressure drop due to friction between two points along the pipeline. Since gas properties change with pressure and temperature, the general flow equation must be applied for short segments of the pipeline at a time. The total pressure drop will be the same of the individual pressure drops.
