## What is The Physical Significance of Grashof Number ?

Grashof Number is a non-dimensional number used both in fluid mechanics and heat transfer. This number is frequently used in cases where natural convection is involved.  It is named after a German engineer Franz Grashof. There are many dimensionless groups or numbers available which come into play according to the respective dominant forces associated with […]

## 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 […]

## 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 […]

## Properties of Fluids & Their Applications

Although you already have some intuition as to the behavior and properties of fluids in everyday situations, we begin this article with a seemingly simple question: From an engineering standpoint, what exactly is a fluid? Scientists categorize compositions of matter in different ways. A chemist classifies materials according to their atomic and chemical structures in the context of the periodic […]
