If you check the Fluid Dynamics syllabus for GATE you will know that this topic has many sub-disciplines including hydrodynamics and aerodynamics. Questions from this topic are asked in GATE ME, GATE CE, ESE, and ISRO exams.

After studying from reliable Fluid Dynamics GATE ME notes, practice Fluid Dynamics GATE questions and answers PDF. It will help you practice different type of questions. Corroborating your knowledge by studying Fluid Dynamics study material for GATE ME will help you in clearing the GATE ME exam while also learning how to solve practical engineering problems for your future jobs.

## Fluid Dynamics Topics For GATE ME

 Topic Explanation Properties of Fluid Density, temperature, and composition are the basic properties of the fluid. There are two different types of properties:Extensive: Dependent on the amount of materialIntensive: Independent of the amount of material Laminar Flow Through Pipe and Plates Low momentum convection and high momentum diffusion characterize laminar flow through plates and pipes. Fluid Machinery The energy stored by a mass of fluid is mainly in the form of intermolecular, kinetic, and potential energy. Any device that converts energy by the fluid into mechanical energy or vice versa is called a fluid machine. Viscosity At a given rate, the resistance of a fluid to deformation is called its viscosity. Buoyancy In a gravity field, the upward force exerted by a fluid on an object immersed is called buoyancy. Hydraulic Turbines A primer mover used for converting the energy of running water into mechanical energy is called a hydraulic turbine. Pelton Wheel Pelton wheel is a type of impulse hydro turbine that is used in hydroelectric plants for operating under high heads. Bernoulli Application The applications of Bernoulli’s principle are:Venturi Meter that measures any liquid’s rate of flow through pipesWorking of airplanes by specifically designing its wings to allow the air to pass at a higher speed from the above surface than the lower.
