# Heat Transfer ## Conduction through slab

Application of Fourier’s Law of conduction Assumptions:→  Steady state Heat Transfer → Temperature, T ≠ f(Time) at a particular point.→ One dimensional conduction→Uniform thermal conductivity ‘k’ Case1: Conduction through a slab T = f(x)Boundary Conditionsat x = 0, T = T1at x = b , T = T2from fourier’s law of conduction q = -kA dT/dxqdx = …

Share the knowledge ## Laws of Heat Transfer

Fourier’s law of conduction Rate of heat transfer by conduction along a given direction is directly poportional to the area of the heat transfer lying perpendicular to the direction of heat transfer. In the above expression, -ve sign denotes that as x↑ T↓ “Heat always flows in direction of downhill of temperature.” k is thermal conductivity. …

In modes of heat transfer, we will learn about the movement of heat from one thing to another by means of conduction, convection or radiation. All forms of heat transfer may occur in some systems at the same time. Heat is the amount of thermal energy that is transferred between two objects due to temprature …
