The formula to calculate the Heat Output (HO) is:
\[ HO = HI \cdot \frac{E}{100} \]
Where:
Heat output refers to the amount of heat energy produced by a system, which is determined by the total heat input and the efficiency of the system.
Let's assume the following values:
Using the formula to calculate the Heat Output (HO):
\[ HO = 5000 \cdot \frac{80}{100} = 4000 \, \text{units} \]
The Heat Output (HO) is 4000 units.
