Fluids are divided into five types they are: Ideal fluids Real fluids Newtonian fluids Non-Newtonian fluids Ideal plastic fluids Ideal Fluids: An ideal fluid is defined as a fluid which is in-compressible and the one that does not have viscosity. Ideal fluids are imaginary fluids. This exist some viscosity. Real Fluids: A real fluid is defined as a fluid which possesses…
Density or mass density, Weight density or specific weight, specific volume and specific gravity are important terms used in Hydraulics and Fluid Mechanics : I. Density or mass density. It is defined as the mass per unit volume of a liquid at a standard temperature and pressure. It is usually denoted by p (rho). It is expressed…
The pressure of a liquid may be measured by the manometers. These are the devices used for measuring the pressure at a point in a liquid by balancing the column of the liquid by the same or another column of liquid. The manometers are classified as follows: 1. Simple manometers such as piezometer and U-tube manometer….
