One hundred, mul/h of butane and 5000 mi/h of air are fee to a combustion reactor. Calculate the perent air The answer is 64.6% am you an unclear at this point: If Instead had been given 61.6% excess air, you could have calculated the feed rate of air as (nair)fed = 11.616)/(1 1.616)/(inair the 25000 theorencal I do not know how this number wur obtained. pleass explain

**Theoretical and Excess Air Calculation**

In an educational setting focused on chemical engineering or environmental science, calculating the amount of air required for combustion is essential. Below is an explanation of a specific problem along with a visual illustration:

---

**Problem Statement:**

- "One hundred m³/h of butane and 5000 m³/h of air are fed to a combustion reactor. Calculate the percent air."

**Solution:**

- The answer provided: **61.9%**

**Clarification Needed:**

- A handwritten note reads: "I am unclear at this point. If excess air was not given 61.9% would not have calculated it."

**Graphical Illustration:**

- A diagram is present showing a "Feed rate of air gas" with a noted calculation: 
  - "Calculated = 5000" 
  
**Note:** This illustrates a rate calculation but lacks further explanation of how the numbers were derived.

**Request for Explanation:**

- A handwritten query: "I do not know how this number was obtained. Please explain."

---

This educational exercise involves understanding how to calculate the air required for the combustion of fuels like butane and clarifying doubts in determining excess air percentages.
