Answer:
Steady flow
Step-by-step explanation:
Flows in fluids can be categorized into different classes depending on the type of flow and the variations in their characteristics such as velocity, pressure, density, temperature, e.t.c
When these characteristics do not change when measured over time at a single point, then the flow is said to be steady. For a steady flow, the mathematical expression, amidst other conditions, is given as follows;

Where;
V, P and T are the velocity, pressure and temperature of the fluid.
PS:
Other types of flows include:
i. Unsteady flow
ii. Laminar flow
iii. Turbulent flow
iv. Uniform flow
v Non-uniform flow
vi. Rotational flow
vii. Irrotational flow
