Question

The volumetric efficiency of a certain engine is 88.5%. This means the actual airflow is 88 5% of the theoretic airflow. If the actual airflow is 232.1 cm (cubic feet per minute), what is the theoretic airflow of this engine?

Answer 1

`Theoretic\text{ airflow = 262.3 cubic ft per minute}`

Step-by-step explanation:

Here, we want to get the theoretic airflow of the engine

From the given question, we have it that the actual airflow is 88.5% of the theoretic airflow

Mathematically:

`\begin{gathered} Actual\text{ airflow = 88.5\% }*\text{ theoretic airflow} \\ \end{gathered}`

We can substitute the value of the actual airflow into the equation above

We have that as:

`\begin{gathered} 232.1\text{ = }(88.5)/(100)* theoretic\text{ airflow} \\ \\ theoretic\text{ airflow = }(100*232.1)/(88.5) \\ \\ theoretic\text{ airflow = 262.3 } \end{gathered}`
