The orientation determines the pressure the wick structure needs to overcome in order to return liquid to the evaporator. It is favorable to have the evaporator below the condenser to have the aid of gravity in the liquid return process.

Heat Pipe Length: in cm mm This is the total length of the heat pipe; generally, this is the sum of the evaporator length, condenser length, and the adiabatic region. The length contacting your heat source. The length contacting your heat sink. Project Title. Close Submit to ACT.Heat transfer through radiation takes place in form of electromagnetic waves mainly in the infrared region.

Radiation emitted by a body is a consequence of thermal agitation of its composing molecules. Radiation heat transfer can be described by reference to the 'black body'. The black body is defined as a body that absorbs all radiation that falls on its surface. Actual black bodies don't exist in nature - though its characteristics are approximated by a hole in a box filled with highly absorptive material.

The emission spectrum of such a black body was first fully described by Max Planck. A black body is a hypothetical body that completely absorbs all wavelengths of thermal radiation incident on it. Such bodies do not reflect light, and therefore appear black if their temperatures are low enough so as not to be self-luminous.

All black bodies heated to a given temperature emit thermal radiation.

Specific Heat Calculator

The radiation energy per unit time from a black body is proportional to the fourth power of the absolute temperature and can be expressed with Stefan-Boltzmann Law as. For the gray body the incident radiation also called irradiation is partly reflected, absorbed or transmitted.

If an hot object is radiating energy to its cooler surroundings the net radiation heat loss rate can be expressed as. Heat loss from a heated surface to unheated surroundings with mean radiant temperatures are indicated in the chart below. This calculator is based on equation 3 and can be used to calculate the heat radiation from a warm object to colder surroundings. A c - object area m 2.

With conduction energy transfers from more energetic to less energetic molecules when neighboring molecules collide.

Heat flows in direction of decreasing temperatures since higher temperatures are associated with higher molecular energy. Thickness of the wall is 50 mm and surface length and width is 1 m by 1 m.

The temperature is o C on one side of the surface and 80 o C on the other. The conductive heat transfer through the wall can be calculated. This calculator can be used to calculate conductive heat transfer through a wall. The calculator is generic and can be used for both metric and imperial units as long as the use of units is consistent. Note that heat resistance due to surface convection and radiation is not included in this equation.

Convection and radiation in general have major impact on the overall heat transfer coefficients. A furnace wall of 1 m 2 consist of 1. The inside surface temperature of the steel is K and the outside surface temperature of the insulation board is K.

Open Calculator.This specific heat calculator is a tool that determines the heat capacity of a heated or a cooled sample.

Specific heat is just the amount of thermal energy you need to supply to a sample weighing 1 kg to increase its temperature by 1 K. Read on to learn how to apply the heat capacity formula correctly to obtain a valid result. If you have problems with the units, feel free to use our temperature conversion or weight conversion calculators.

You don't need to use the heat capacity calculator for the most common substances. The values of specific heat for some of the most popular ones are listed below. Having this information, you can also calculate how much energy you need to supply to a sample to increase or decrease its temperature. For instance, you can check how much heat you need to bring a pot of water to boiling so that you can cook some pasta. Wondering what the result actually means? Try our potential energy calculator to check how high you would raise the sample with this amount of energy.

Or check how fast could the sample move with this kinetic energy calculator. Specific Heat Calculator can be embedded on your website to enrich the content you wrote and make it easier for your visitors to understand your message. Get the HTML code. Omni Calculator logo Embed Share via. Energy Q.

Table of contents: How to calculate specific heat Heat capacity formula Typical values of specific heat. How to calculate specific heat Determine whether you want to warm up the sample give it some thermal energy or cool it down take some of this energy away.

Insert the amount of energy supplied as a positive value. If you want to cool down the sample, insert the subtracted energy as a negative value. For example, we can assume that we want to reduce the thermal energy of the sample by J.

Decide what will be the temperature difference between the initial and final state of the sample and type that into the heat capacity calculator. If the sample is cooled down, the difference will be negative, and if warmed up - positive. Let's say we want to cool the sample down by 3 degrees. You can also go to advanced mode to type the initial and final values of temperature manually.

Determine the mass of the sample. This is the typical heat capacity of water. Typical values of specific heat You don't need to use the heat capacity calculator for the most common substances.
