Construction and working of drilling machine
Working Principle of Drilling Machine: It is a machine which is used to drill the holes on the components or workpiece with the help of drill bits. The drill bits…
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…
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…
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…
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…
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…
What’s the difference between the brake and the clutch?
Brake and clutch are the two different components used in automotive . These two elements serve two different purposes. Though their functions are entirely different, both are needed for the smooth running of…
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…
What is Draft Tube ? Describe its Functions and Classifications
In hydraulic turbines, the component draft tube is very significant. In impulse turbines, the flow energy of the fluid is converted to kinetic energy by means of the nozzle. In Reaction Turbines,…
Ten Tools Every Welder Wants
This article is all about the tools that welders want to have in their shop. They make welding easier, and in many cases, they make the welding process — from…
