In fluid mechanics, a system is said to be in a steady state if the fluid flow variables (such as velocity, pressure, and temperature) do not change with time. That is, the fluid flow is constant in time. In order to achieve a steady state, the fluid must be in thermal and mechanical equilibrium.

### Q: What is steady state in fluid mechanics?

A: In fluid mechanics, steady state is a condition in which the fluid flow is constant in time. This means that the fluid flow rate and velocity are constant, and there is no net change in the fluid properties.

### Q: What is a steady state system?

A: A steady state system is one in which the system’s state does not change over time. In other words, the system is in equilibrium.

### Q: How do you know if a flow is steady?

A: There are a few ways to determine if a flow is steady. One way is to look at the flow field and see if there are any areas of change or movement. Another way is to take measurements of the flow over time and see if the values are consistent.

### Q: What is a steady state single flow process?

A: A steady state single flow process is a process in which there is a constant rate of flow of material or energy through a system, and there is no net accumulation of material or energy within the system.
