In most engineering courses, when dealing with flow devices like pumps, heat exchangers, turbines, and compressors, we commonly assume "Steady State and Steady Flow".

Here's why:

1. Steady State: This means that all the state variables (like pressure, temperature, density, etc.) are constant in time. In other words, the system has reached an equilibrium and is not changing with time. This is a common assumption because it simplifies the analysis of these devices.

2. Steady Flow: This means that the flow of fluid through the device is constant over time. This is also a common assumption because these devices are typically designed to operate at a certain flow rate.

The assumption of constant temperature is not typically made because these devices often involve energy being added or removed, which would change the temperature.
