A venturi meter is a flow measuring equipment or gadget that is used to measure the discharge of liquid through a pipe. It is based on Bernoulli’s principle. Construction: A venturi meter is essentially a small pipe with two conical portions and a short segment of the uniform cross-section in between, as shown in Fig. … Read more
The orifice meter is made-up of chrome steel, phosphor bronze, nickel, and monel. An orifice meter provides an easier and cheaper arrangement for the measurement of flow through a pipe. An orifice is a thin circular plate with a sharp-edged concentric circular hole in it. The main part of an orifice flow meter may be a chrome steel orifice plate which is held … Read more
The change in velocity of the fluid in a flow (either in magnitude or direction) induces large-scale turbulence due to the formation of eddies. So, a portion of energy possessed by the flowing fluid is ultimately dissipated as heat by radiation and is considered to be the loss of energy. Some of the reasons for … Read more
Bernoulli’s Theorem Bernoulli’s theorem is the principle of energy conservation for ideal fluids in steady or streamlined inflow. This theorem describes the relationship among pressure, haste, and elevation in a moving fluid similar to liquid or gas. According to this theorem, the compressibility and density ( internal disunion) are negligible and the inflow is steady, … Read more

Reynolds number The non-dimensional parameter called Reynolds number was discovered by an Irish engineer and physicist, Osborne Reynolds, in 1883. He identified the fundamental dimensionless parameter that characterizes the behavior of flowing fluids, known as the Reynolds number. It was the ratio that shows the effect of viscosity in a given medium that governs the … Read more
What is manometer The term manometer comes from the Greek words’manós’, which means thin or rare, and’métron,’ which means measure. A manometer is a device that measures the pressure (static pressure) exerted by a still liquid or gas based on the idea of hydrostatic equilibrium. The pressure at any location in a fluid at rest … Read more
Standard deviation The concept of Standard deviation was introduced by Karl Pearson in 1893. In Statistics, Standard deviation is the measure of dispersion of a set of data from itsmean. It measures the absolute variability of a distribution or how much your data is spread outaround the mean or average. More precisely, Standard deviation is … Read more
Flow of fluids The flow of fluids: Fluid is a substance similar to a gas or a liquid that has no fixed shape and flows fluently upon operation of external pressure. Flow is defined as the act of moving on in a steady, nonstop sluice. Therefore, fluid inflow is a part of fluid mechanics that deals with fluid dynamics and is a stir of feasts and liquids. The stir of fluid is due to unstable forces, and this stir continues as long as unstable forces are applied. For illustration, if you’re pouring water from a teacup, the haste of water is veritably … Read more
Hair fall is one of the main problems in men and women, not only genetic problems but also in our daily life practices, like food, the water we use, weather and environment, etc are the main reason for hair fall or hair loss. Due to hair loss problems, people feel uncomfortable. Hair replantation is not … Read more
