Reciprocating Pumps: Parts, Diagram, Types and Working Principle | Fluid Mechanics

Reciprocating Pumps: Parts, Diagram, Types and Working Principle! Introduction to Reciprocating Pumps: A reciprocating pump is a positive displacement pump. This means, the liquid is first sucked into a cylinder and then displaced or pushed by the thrust of a piston or plunger. The pump consists of a cylinder and a piston. The cylinder is in communication with suction and [...]

Forces Exerted by Moving Fluid on Immersed Bodies: Drag and Lift and Submerged Objects| Fluid Mechanics

When a body is placed in a moving fluid, a force is exerted on the body by the moving fluid. Similarly when a body moves within a fluid at rest then also a force is exerted on the body by the fluid. Motion of submarines, torpedos and aeroplanes are examples of this kind. Consider a body placed in a fluid [...]

Impact of Jet on a Plate or Vane: Notes and Viva Questions| Fluid Mechanics

Impact of Jet on a Plate or Vane: Notes and Viva Questions. Introduction to Jet: A jet of water issuing from a nozzle has a velocity and hence it possesses a kinetic energy. If this jet strikes a plate then it is said to have an impact on the plate. The jet will exert a force on the plate which [...]
