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.

define- fluid, density,weight density,specific volume,specific gravity property of fluid

what is fluid. Fluid mechanics is the branch of the scince that deals with the fluid's behavior (liquid or gases) both in rest and in motion. This branch of science is therefore concerned with the static, kinematic and dynamic elements of fluids. Rest fluid research is called static fluid study. Fluid in movement research where pressure force is not regarded is called fluid kinematics, and if pressure force is also regarded for liquids in movement, that branch of science is called fluid dynamics. 2. properties of fluid. (a). density or mass density:- (b). specific weight or weight density:- (c). specific volume:- (d). specific gravity:- (a). density or mass density:- The density or mass density of the fluid is described as the proportion of the mass of the fluid to its volume, hence the density of the mass per unit volume of the fluid. it is denoted by the symbol rho( ρ). the unit of mass density in SI unit is kg/cu...

problem:- A circular tank of diameter 4m contains water up to a height to 5m. Orifice of diameter 0.5m at the bottom. Find the time taken by water:- 1. To fall from 5m to 2m 2. For completely emptying to tank take cd=0.6

What is plasticity index.

· What is plasticity index:- The plasticity index is the range of water content which the soil is plastic. it is difference between LL and PL . it is a number no unit. PI = LL – PL Or, pi = wL – wP for cohesion less soil, PI is zero as they have no plastic stage.
