Question
### Problem 23.10 A sewer pipe must be laid starting from an invert elevation of 784.58 ft at station 9 + 25 to an ending invert elevation of 782.48 ft at station 12 + 75. Determine the uniform grade needed, and calculate invert elevations at each 50-ft station. **Explanation** 1. **Starting Point**: Invert elevation is 784.58 ft at station 9 + 25. 2. **Ending Point**: Invert elevation is 782.48 ft at station 12 + 75. 3. **Task**: - Determine the uniform grade required. - Calculate invert elevations at every 50-ft station. **Instructions** - **Uniform Grade Calculation**: - Find the difference in station numbers and the total distance. - Use the change in elevation and distance to calculate the slope. - **Invert Elevations**: - Using the calculated uniform grade, determine elevations at each 50-ft increment between the starting and ending stations.
