## What is meant by thermal resistance explain the electrical analogy for solving heat transfer problem?

What is meant by thermal resistance explain the electrical analogy for solving heat problems? **The rate of heat transfer through a layer corresponds to the electric current**, the thermal resistance corresponds to electrical resistance, and the temperature difference corresponds to voltage difference across the layer.

## What is the correct analogy for heat flow?

Heat flow has an analogy **in the flow of electricity**. Ohm’s law states that the current ‘I’ flowing through a wire is equal to the voltage potential (E1 – E2) divided by the electrical resistance Re. Where Rth = L k A is the conductive thermal resistance to heat flow offered by the wall.

## What are the analogy between heat and mass transfer?

The proposed analogy between heat and mass transfer is **applied to predict a temperature-dependent heat-transfer coefficient from the temperature-dependent mass-transfer coefficient in the constant-rate period during non-convective drying of the suspension**.

## What are the analogies for electrical parameters?

There are two types of electrical analogies of translational mechanical systems.

## What are the three different types of heat transfer?

**Heat can be transferred in three ways: by conduction, by convection, and by radiation.**

- Conduction is the transfer of energy from one molecule to another by direct contact. …
- Convection is the movement of heat by a fluid such as water or air. …
- Radiation is the transfer of heat by electromagnetic waves.

## Can an AC supply be used to describe the electrical analogy of heat conduction?

Enquiry about Electrical Analogy Of Heat Conduction

The temperatures in heat conduction **are analogous to voltages at corresponding points**. … The current through electrical circuit is analogous to flow of heat, Q and the electrical resistance corresponds to thermal resistance.
