## Fluid Mechanics – Gas Laws

Gas laws are first equation of state that shows relationship temperatures and pressures of gases. Gas Laws explain about changes in behavior of gas when certain conditions are applied. Gas laws deal with how gases behave with respect to volume, pressure, temperature and amount. Following are some of important gas laws. Boyle’s Law Charles’ Law Gay-Lussac’s Law or Amontons’ Law

## Viscosity in Fluid Mechanics

Viscosity is friction of fluids and it also describes internal resistance of flow of fluid. In this article, we are going to discuss what dynamic viscosity and kinematic viscosity are, their definitions, applications of dynamic and kinematic viscosity and finally differences between kinematic viscosity and dynamic viscosity. What is Viscosity? Viscosity can be defined as resistance of fluid to flow.

## Bernoulli’s principle from Equation in Fluid Mechanics

In fluid dynamics, Bernoulli’s principle state that an increase in fluid speed occurs with pressure decrease or decrease in fluids potential energy. This principle can be applied to many types of fluid flow as result in various forms of Bernoulli’s equation. So far, we have discussed fundamental aspects of Bernoulli equation. This article is about Bernoulli’s principle and equation in

## Pressure Scales in Fluid Mechanics

In fluid mechanics, pressure is one of basic properties of all fluids. Pressure (P) is defined in simplest terms as force (F) per unit area. Units of pressure are N/m which is called Pascal (Pa). However, it is small unit, so it is convenient to work with many of Pascal like kPa, the bar and MPa. In this article, we

## Brake System Types, Functions, Types of Brakes in automobile

Brake system is most important parts of a vehicle. This braking system is necessary in an automobile for stopping vehicle. Brakes are applied on wheels to stop or to slow down the vehicle by converting its kinetic energy into heat. No matter what kind of vehicle people use, an efficient braking system will always use for safety. In this article,

## Difference between Diesel and Petrol Engine

Petrol and diesel engines are two common things used internal engines. Petrol and diesel engine is done on basis of fuel used by these engines. Engine which uses petrol is called petrol engine but engine that uses diesel is called diesel engine. In this article, we will discuss about differences between petrol and diesel engine. There is lot of variation

## Low Engine Oil Pressure and How to repair low oil pressure

In automobile, oil is used to protect engine. When it comes to engines, oil is product to controls inner activities that occur within engine. Lack of oil leads to overheating as well as engine parts are down. So to avoid set-up of oil pressure, you need to understand reasons that lead to low oil pressure in engines. In this article,
