Pressure-Velocity Graph for Impulse and Reaction Turbine Explained
The turbine are mainly of two types – Impulse and Reaction Turbine. In Impulse Turbine the hydraulic energy of the fluid is converted to kinetic energy through a nozzle. The jet created by the nozzle runs the turbine blades. In reaction turbine no nozzle is used. A part of the total available energy is converted […]
Basic Mechanical Questions (IC Engines) Part – 6
Welcome to the sixth part of sixth part of basic mechanical questions. These questions are useful for interview purpose and also for written exams. Hope you will be benefited from this. Lets begin – What is the difference between turbocharger and supercharger ? Ans : Turbocharger and Supercharger both have the same function. These devices […]

A Complete Guide to Fluid Mechanics Fundamentals and Applications
In this section, we introduced the physical properties of fluids, the distinction between laminar and turbulent flows, and the forces that are known as buoyancy, drag, and lift. Mechanical engineers categorize substances as being either solids or fluids, and the distinction between the two centers around how they respond to a shear stress. You’ll find details […]
Aerodynamics in Sports
When a ball is hit, thrown, or kicked in sports, the ball’s trajectory can rapidly change direction.In baseball, this phenomenon is the strategy behind curve ball pitches; in golf, it is responsible for slicing or hooking a ball driven off a tee; and in soccer, the ball can be “bent” during a free kick to […]
Lift Force – Aerodynamics Fundamentals
LIFT FORCE Similar to drag, the lift force is also produced by the relative motion between a solid object and a fluid. While the drag force acts in parallel to the direction of the fluid’s flow, the lift force acts in perpendicular to it. For instance, in the context of the airplane shown in Figure […]
Drag Force Equation in Aerodynamics
When mechanical engineers design automobiles, aircraft, rockets, and other vehicles, they generally need to know the drag force FD that will resist high-speed motion through the air or water. In this section, we will discuss the drag force and a related quantity that is known as the coefficient of drag, denoted by CD. That parameter quantifies the extent […]
Blood Flow in the Body – An Application of Fluid Engineering
The flow of blood within the human body is an interesting application for these principles of fluids engineering. The circulatory system is regulated in part by muscles in the arterial walls that contract and expand to control how much blood will flow through different parts of the body. Blood pressure is determined by the output of the heart and by the extent […]
Principles of Fluid Flows in Pipes- Pressure Drop & Flow Rate
A practical application for the concepts of pressure, viscosity, and the Reynolds number is the flow of fluids through pipes, hoses, and ducts. In addition to distributing water, gasoline, natural gas, air, and other fluids, pipe flow is also an important topic for biomedical studies of the human circulatory system (Figure). Blood flows through the arteries and veins in […]
What is Pressure and Buoyancy Force – Fluid mechanics
The forces known as buoyancy, drag, and lift arise when fluids interact with a solid structure or vehicle. Drag and lift forces arise when there is relative motion between a fluid and a solid object. A vehicle can either move through the fluid (as an aircraft moves through air,for instance) or the fluid can flow […]
