Kaplan Turbine | Working, Advantage, Disadvantage, Application, Parts

What is a Kaplan Turbine? Kaplan turbine is a propeller type, axial flow water turbine. It has adjustable blades. Adjustable blades help in obtaining good efficiency at wide range of head and discharge available to the turbine. It is suitable for low head and high flow applications. It is an evolution of Francis turbine. It is… Read More »

Francis Turbine | Working, Advantage, Disadvantage, Application, Parts

What is a Francis Turbine? A Francis Turbine is a type of reaction turbine in which inward flow (of water) is mixed. Mixed flow means a combination of both axial and radial. It is mainly used for electrical power generation.

Planer Machine | Working Principle, Types, Applications

What is a Planer Machine? A planer machine is a type of metal working machine that uses linear relative motion (reciprocation) between the workpiece and a single-point cutting tool to cut the work piece. A planer is very much similar to a shaper but there are some basic differences. A Planer Machine is larger and… Read More »

Lead Screw | Applications, Advantages, Disadvantages, Types

What is a lead screw? Lead screw is a type of screw which is used as linkage in machines. It converts rotary (or turning) motion into linear motion. Due to large contact area between male and female members of a lead screw, it has very high frictional losses. Image source: By Orion Lawlor – Own work,… Read More »

Buoyancy | Archimedes Principal | Examples & its Calculation

What is buoyancy? Buoyancy is the force exerted by a fluid on a body which is wholly or partially immersed in it. How buoyancy force is calculated? Magnitude of buoyancy force is calculated on the basis of Archimedes principal. What is Archimedes principal (or Law)? The magnitude of buoyancy force acting on a body is… Read More »
