Properties of Fluids

Properties of Fluids

Properties of fluids determine how fluids can be used in engineering and technology. They also determine the behaviour of fluids in fluid mechanics. The following are some of the important basic properties of fluids: Density Viscosity Temperature Pressure Specific Volume Specific Weight Specific Gravity 1. Density: Density is the mass per unit volume of a fluid. [...]

Fluid - Definition and Types

Fluid – Definition and Types

Fluid is a substance that is capable of flowing. It has no definite shape of its own. It assumes the shape of its container. Liquids and gases are fluids. Types of Fluids: Fluids can be classified into four basic types. They are: Ideal Fluid Real Fluid Newtonian Fluid Non-Newtonian Fluid 1. Ideal Fluid: An Ideal [...]

Introduction to Gas Power Cycles

Introduction to Gas Power Cycles

A thermodynamic cycle is a sequence or series of processes performed on a system, that eventually returns the system to its original state. Gas power cycles are thermodynamic cycles, which use air, as the working fluid. A gas power cycle may consist of heat transfer, work transfer, pressure variations, temperature variations, volume variations and entropy [...]

Shaper

Shaper

A shaper (or shaping machine) is a reciprocating type of machine. It is used for removing unwanted material and producing flat surface on a given workpiece. In a shaper, a single point cutting tool undergoes linear reciprocating motion over a stationary workpiece. A driving mechanism is used to achieve reciprocating motion. The three commonly used [...]
