Introduction to open channel flow and its practical application: Open channel flow is defined as the flow of a liquid with a free surface i.e. surface having constant pressure such as atmospheric pressure. Rivers, streams, canals and irrigation ditches are the example of open channel flow. Difference between open channel and pipe flows: Open channel … Read more
Buoyancy: When a body is immersed in fluid an upward force is exerted by the fluid on the body. This upward force is equal to the weight of the fluid displaced by the body is called the force of buoyancy or buoyancy. Center of Buoyancy: It is defined as the point through which the force … Read more
What is Total pressure force and Center pressure force? Total pressure: Total pressure is defined as the force exerted by a static fluid on a surface either plane or curved when the fluid comes in contact with the surface. This force always acts normal to the surface. Centre of pressure: Centre of pressure is defined … Read more
Introduction, intensity of pressure Fluid Pressure at a point Source:http://wwwmdp.eng.cam.ac.uk/web/library/enginfo/aerothermal_dvd_only/aero/fprops/statics/node4.html Consider a small area dA in large mass of fluid. If the fluid is stationary, then the force exerted by the surrounding then the force exerted by the surrounding fluid on the area dA will always be perpendicular to the surface dA. Let, dF is … Read more
Fluid Mechanics: Fluid mechanics is the branch of science which deals with behavior of fluid (gaseous or liquid). Fluid Mechanics Divided into: a. Fluid Statics It is the study of fluid at rest. b. Fluid Kinematics It is the study of fluid in motion but we don’t consider any forces. c. Fluid Dynamic It … Read more
