# qcond: Estimates the area specific heat transfer by conduction... In Thermimage: Thermal Image Analysis

## Description

Estimates the area specific heat transfer by conduction (W/m2). Positive

## Usage

 `1` ```qcond(Ts = 30, Tc = 20, ktiss = 0.502, x = 1) ```

## Arguments

 `Ts` Surface temperature (degrees Celsius). Default value is 30. `Tc` Contact temperature (degrees Celsius), usually ground temperature. Default value is 20. `ktiss` Thermal conductivity of tissue (W/m/oC). `x` Distance over which heat is conducted. Default value is 1 m (unrealistic, but easier for converting)

## Details

Usually conductive heat transfer is ignored given little surface area will be in contact with the ground, but this is included for functionality.

## Examples

 ```1 2 3 4 5 6``` ```## The function is currently defined as function (Ts = 30, Tc = 20, ktiss = 0.502, x = 1) { qcond <- ktiss * (Tc - Ts)/x qcond } ```

### Example output

```function (Ts = 30, Tc = 20, ktiss = 0.502, x = 1)
{
qcond <- ktiss * (Tc - Ts)/x
qcond
}
```
