## What is Hydraulic Machine?

Hydraulic machine are those machines which convert hydraulic energy (energy possessed by water) into mechanical energy (which is further converted into electrical energy) or mechanical energy into hydraulic energy. The hydraulic machines, which convert the hydraulic energy into mechanical energy, are called turbine while the hydraulic machines which convert the mechanical energy into hydraulic energy […]

## What is Use of Heat Conduction Equations?

Heat conduction equation is defined as the differential equation through which we can define the conduction in any shape of body and we can calculate the temperature at any point in a medium in any situation like steady flow, transient flow, one dimension flow, three dimension flow etc. It is governing equation of conduction. There

## What is Heat Transfer?

To know about heat transfer first we must know about energy. Energy is the ability to do work or produce power to do work . Energy can neither be created nor be destroyed but it can change from one from to another. Energy can exist in various forms like mechanical energy, chemical energy, electrical energy, nuclear

## Basic Introduction About Heat Transfer

We all know that heat is the form of energy and it can be transfer from one body to another by virtue of temperature difference. The branch of science in which we study about transfer of heat is known as heat transfer. Why should we know about heat transfer? Heat transfer is required to know

## What is Stress in Mechanics of Solids ?

In order to understand the subject mechanics of solids (or strength of materials) , first we must know the meaning of strength of materials. When an external force is applied on the body in the form of push or pull, the body tends to undergo some deformation. But due the existence of cohesive forces between
