Explain the velocity of liquids
WebThis device is used to measure velocities and mass rate of flow of liquid at the different cross-sections of a pipe. It consists of a constriction inserted in a pipe line and have tapers at the inlet and outlet, so that turbulence is avoided. See fig. 11.21. WebA fluid’s motion is affected by its speed, density, and viscosity, and weight, as wells as drag and lift. Use an example of a pipe with different sized openings on either end to observe …

WebOct 19, 2015 · The change in velocity also affects the pressure of the fluid. To understand why, we can turn to Bernoulli’s principle. This principle states that within a specified flow field, a decrease in pressure occurs when there is an increase in velocity. The pressure difference described by the Venturi effect is utilized in many different devices. WebFigure 1. Flow rate is the volume of fluid per unit time flowing past a point through the area A. Here the shaded cylinder of fluid flows past point P in a uniform pipe in time t. The volume of the cylinder is Ad and the average velocity is. \overline {v}=d/t\\ v= d/t. so that the flow rate is. Q=\text {Ad}/t=A\overline {v}\\ Q= Ad/t=Av.
WebJun 15, 2024 · Flow velocity is the vector field that is used to describe fluid motion in a mathematical manner. The entire length of the flow velocity is referred to as the flow … WebFluid flow can be steady or unsteady, depending on the fluid’s velocity: Steady: In steady fluid flow, the velocity of the fluid is constant at any point. Unsteady: When the flow is unsteady, the fluid’s velocity can differ between any two points. Properties of fluid explain three main properties and they are kinematics, …
WebIt is the energy possessed by a liquid by virtue of its motion. If m is the mass of the liquid moving with a velocity v, the kinetic energy of the liquid = 1/2 mv2. Kinetic energy per unit mass = 1/2mv2/m =v2/2. Potential energy It is the energy possessed by a liquid by virtue of its height above the ground level. Webthe relative velocity between fluid and solid, the shape of the solid, the density of the gas and its viscosity. The power required to move a fluid through a conduit is a function of the …
WebWe assume that the slipping plane, at which the liquid velocity u relative to the particle ( u → -U as r →∞) is zero ( u = 0) coincides the particle surface at r = a. Then the above …
