Class 8 Science quiz, Chapter wise Gravity affects the fluid pressure by causing the fluid body to flow throughout the direction or orientations of its own net acceleration. The several layers in the fluid flow with different velocities which in turn causes friction to arise between the layers thus causing the loss of energy. The angle of Contact is defined as the angle subtended between the tangents drawn at the liquid surface and the solid surface inside the liquid at the point of contact. In order to change the shape and size of the solid object, an external force needs to be applied. At the critical temperature, the surface tension reduces to zero. Basically for an incompressible fluid flowing in a streamline flow, the sum of pressure energy per unit mass, kinetic energy per unit mass (related to velocity change), and potential energy per unit mass (related to height change) is a constant.

Education, Karnataka Examination The speed at which the falling object reaches when the gravity and the air resistance is equal on the object then it is known as the critical velocity. As a result, when an incompressible fluid passes through a pipe with a non-uniform cross-section every second, the volume is equal to the steady flow. Hooke's law is an empirical law that holds true for most materials. If the flow speed of the fluid reaches beyond a certain critical speed, the flow no longer remains steady but changes to turbulent flow. V: Initial volume of the material in the units of in the English system and N/m2 in the metric system. Fluid Mechanics A flowinmg liquid may be regarded as consisting of a number of layers one above the other.Fluid Mechanics is of fundamental importance as it talks both about the fluids both at rest and in motion.
