### Problem Statement:
**Q1//** Two stages of air streams mixing adiabatically, shown in Figure attached. Find all the properties of the resultant air at point 3 and point 5.

*Note: Write the correct solution and the required answers. Answers should be given in parentheses for each point without mentioning the equations. Grade of the question (50 degrees).*

#### [Figure Explanation]:

The figure illustrates the adiabatic mixing of air streams in a two-stage process, depicted with labeled flow points:

1. **Point 1**: 
   - Temperature (T\1) = 32°C
   - Relative Humidity (RH\1) = 40%
   - Flow Rate = 20 m³/min

2. **Point 2**: 
   - Temperature (T\2) = 12°C
   - Relative Humidity (RH\2) = 90%
   - Flow Rate = 25 m³/min

3. **Point 3**:
   - Resultant Point from the mixing of Point 1 and Point 2.

4. **Point 4**: 
   - Temperature (T\4) = 8°C
   - Relative Humidity (RH\4) = 30%
   - Flow Rate = 15 m³/min
   
5. **Point 5**:
   - Resultant Point from the mixing of Point 3 and Point 4.

#### Given Data:
- Mixing process is adiabatic.
- Pressure (\P_r\) = 1 atm

You are expected to find:
- The temperature, humidity, and any other properties of the resultant air at **Point 3**.
- The temperature, humidity, and any other properties of the resultant air at **Point 5**.

This problem can be utilized for learning purposes related to the study of thermodynamics, particularly focusing on air mixing at specific conditions and calculations of resultant properties in a controlled environment.

##### Note:
The given diagram may contain flow arrows and numerical values indicating specific conditions at various points, essential for solving the problem.
