What is Draft Tube ? Describe its Functions and Classifications
http://emaevents.co.uk/*/event-burn-out-and-self-care-week?unapproved=5500 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, part of the flow energy is converted to K.E but remaining energy is still the pressure energy. Draft tubes are used in Reaction turbines to [...]

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 a automotive vehicle . What is Brake ? Simple Principle of Braking System Brakes are generally used to halt the rotating wheels [...]
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 [...]

What is Cooling Tower ? Describe With Schematic Diagrams
Cooling tower is a device which is used to extract waste heat by the stream of water of low temperature. The cooling system of the cooling tower is known as the evaporative cooling system. In this process small amount of heat is rejected by evaporation and the most of the heat is rejected by the stream of water. Most of the times water [...]
