Final answer:
The total heat release rate for a pool of a combustible liquid is determined by multiplying the rate of heat release per unit area by the total Area of the pool.
Step-by-step explanation:
The total heat release rate for a pool of a combustible liquid is the rate of heat release per unit area multiplied by the Area of the pool.
This is because the total heat released is proportional to the size of the surface area that is burning. The rate of heat transfer by emitted radiation can be expressed using the Stefan-Boltzmann law, but for calculating the total heat release rate of a combustible liquid's pool, we primarily need to know the heat release rate per unit area and multiply that by the entire area involved in the combustion.
