### Pressure Loss Calculation for Compressed Air Flow

**Problem Statement:**
A compressor delivers 180 scfm of air through a 3/4-in schedule 40 pipe at a receiver pressure of 85 psig. Find the pressure loss for a 170-ft length of pipe.

**Hint: Use the table shown if needed.**

#### Table of Inside Diameter and Corresponding Values of \( d^{5.31} \) for Schedule 40 Common Pipe:

| Nominal Pipe Size (in) | Inside Diameter \( d \) (in) | \( d^{5.31} \) |

*Tabulated values of \( d \) and \( d^{5.31} \) for schedule 40 common pipe.*

**Explanation of the Table:**
- **Nominal Pipe Size (in):** This column lists the standard nominal sizes of pipes measured in inches.
- **Inside Diameter \( d \) (in):** This shows the actual inside diameter of the pipes in inches.
- **\( d^{5.31} \):** This column gives the value after raising the inside diameter \( d \) to the power of 5.31, which is used for certain fluid flow calculations.

### Calculation Steps

1. **Identify the Nominal Pipe Size:**
   - From the problem, the nominal pipe size is 3/4 inch.
   
2. **Find the Inside Diameter \( d \) and
