Of course, I will proceed step by step for you.

Given:
- Diameter D = 101.6 \, \text{mm} = 0.1016 \, \text{m}
- Flow rate Q = 5.663369322 \, \text{m}^3/\text{min}
- Length L = 9624.71681499723 \, \text{kg}
- Specific gravity S = 1.0

### Step 1: Convert D from millimeters to meters
D = \frac{101.6 \, \text{mm}}{1000} = 0.1016 \, \text{meters}

### Step 2: Calculate Q^2
Q^2 = (5.663369322 \, \text{m}^3/\text{min})^2 = 32.07375207737074 \, \text{m}^6/\text{min}^2

### Step 3: Calculate the numerator L \cdot S \cdot Q^2
\text{Numerator} = L \cdot S \cdot Q^2 = 9624.71681499723 \times 1.0 \times 32.07375207737074
\text{Numerator} = 9624.71681499723 \, \text{kg} \cdot \text{m}^6/\text{min}^2

### Step 4: Calculate the denominator D^5
\text{Denominator} = D^5 = (0.1016)^5 = 1.0826012887285758 \times 10^{-5} \, \text{m}^5

### Step 5: Solve for P
P = \frac{\text{Numerator}}{\text{Denominator}} = \frac{9624.71681499723}{1.0826012887285758 \times 10^{-5}} \approx 889,036,149.8 \, \text{kilopascals}

Therefore, the backpressure P calculated step by step is approximately 889,036,149.8 kilopascals.

\boxed{P \approx 889,036,149.8 \, \text{kilopascals}}
