Today we will discuss about temperature measuring devices. Temperature is a physical quantity which is defined as the hotness or coldness of any object or substance. We can calibrate temperature in different scales and in different units according to our requirements. Kelvin (k) is the international system of units (SI) of temperature, other than Kelvin …

Brake is a mechanical device which is used to absorb the energy from a moving system by means of friction. The main purpose of brake is to slow down or completely stop the motion of the moving system like wheels of automobiles, rotating drum and any kind of machinery. We can say that brakes are …
The hydraulic intensifier is a mechanical device which is used to increase the intensity of pressure of the fluid. It utilizes the energy of large quantity of liquid at low pressure. Some hydraulic machines require high pressure for working but this high pressure can’t be obtained by using pump. Some of these hydraulic machines are …
As we all heard about different types of power plants which are used for power generation by using different kinds of fuels like steam power plant, hydro power plant etc. like all of these power plants one type of power plant which is developing very fast is known as Nuclear power plant. Nuclear power plant …

Pressure is defined as the normal force exerted by a fluid per unit area of the surface. This pressure can be measured with various techniques using different types of devices. In case of fluid mechanics, we use some specific pressure gauges for measurement of pressure. Selection of pressure gauges depends upon the location and type …
Francis and Kaplan both the turbines come under category of reaction turbine i.e. both kinetic and pressure energy require for the power generation. In both the cases hydraulic energy of water gets converted into useful power output so these are also known as hydraulic turbine. Francis turbine is old turbine. The invention of Kaplan turbine …
Francis turbine is a type of hydraulic turbine which is used to convert hydraulic energy of water into mechanical energy. This mechanical energy is further used for different purpose like electricity generation. Francis turbine is a type of reaction turbine i.e. here pressure is not remain same throughout the turbine. Francis turbine is named on …

Venturi meter is a device used to measure the flow rate or discharge of fluid through a pipe. Venturimeter is an application of Bernoulli’s equation. Its basic principle is also depends on the Bernoulli equation i.e. velocity increases pressure decreases. The principle of venture meter is firstly developed by G.B. Venturi in 1797 but this …
As we all know about the turbine. They have vast application and can be classified in different ways. According to water flowing through the turbine runners, turbines are classified in two categories i.e. impulse turbines and reaction turbines. Pelton wheel turbine is the type of impulse turbine but here we talk about only reaction turbine. …
