Note:

This calculator determines the **Specific Volume** of an extinguishing agent based on temperature. It helps in understanding how the agent expands or contracts with temperature variations, which is crucial in fire suppression system design.

Inputs:

• k1: A constant specific to the extinguishing agent.
• k2: A constant that defines the change in specific volume per unit temperature.
• Temperature (T): The temperature in appropriate units.

Table of Constants

Here are some examples of k 1 k 1 ​ and k 2 k 2 ​ values for different agents:

Generic Name	Trade Name	\( k_1 \) (SI units)	\( k_2 \) (SI units)
HFC-227ea	FM-200	0.1268	0.0005133
FK-5-1-12	Novec-1230	0.0664	0.0002743
CO₂	CO₂	0.1478	0.00057

Enter the values and click **Calculate Specific Volume** to see the result.
