What is active earth pressure?

· What is active earth pressure?

The pressure, which the soil develops in response to the movement of the earth retaining structure away from it, is called active earth pressure.

This is the minimum pressure, because earth pressure does not decrease beyond the active state with further movement of the earth retaining structure.

Write the names of different types of flow

Write the names of different types of flow and explain them. The fluid flow is classified as:- 1. Steady and unsteady flow 2. Uniform and non-uniform flow 3. Laminar and turbulent flow 4. Compressible and incompressible flow 5. Rotational and irrotational flow 6. One,two and three dimensional flow (1). Steady flow:- Study flow is defined as flow types in which fluid characteristics like velocity, pressure, density, etc. at a point do not change over time. Unsteady flow:- Unsteady flow is the type of flow in which the speed, pressure or density at a point changes over time. (2). Uniform flow:- Uniform flow is defined as the type of flow in which the velocity does not change in space at any point. ...
