The formula to calculate the Specific Internal Energy (Es) is:
\[ \text{Es} = \frac{\text{TE}}{\text{TM}} \]
Where:
Let's say the total internal energy (TE) is 5000 joules and the total mass (TM) is 2 kg. Using the formula:
\[ \text{Es} = \frac{5000}{2} = 2500 \, \text{J/kg} \]
So, the Specific Internal Energy (Es) is 2500 J/kg.
