As shown in the Google Maps, a 12-inch PVC pipeline (f = 0.019) will be constructed to provide water from the Pomona Water Reclamation Plant (PWRP) to Cal Poly Pomona campus. The pipeline is meant to deliver 2550 gal/min to the proposed development. The total length of this pipeline is 2.34 miles. The elevations at the beginning point and the ending point are 348 feet and 365 feet, respectively. At PWRP, there is a half-open gate valve for water supply shortly after the flow enters the pipeline through the entrance (r/d = 0). Along the pipeline, smooth bends (with vanes, r/d = 8) were utilized to alter flow direction. At each fire hydrant (FH) location, a tee is installed to create a lateral to the fire hydrant. How much residual pressure should be there at the beginning point to ensure the minimum residual pressure of 30 psi at the ending point of this pipeline? Assume a = 1.0 at all locations; temperature is 15°C. Hint: Compute the pipeline velocity, unit head loss, and the residual pressure (accounting for both major and minor head losses) for this pipeline. Olive Ridge Einstein Bros.

Question
### Pipeline Configuration and Pressure Calculation **Overview:** A 12-inch PVC pipeline (with a friction factor, f = 0.019) is planned to deliver water from the Pomona Water Reclamation Plant (PWRP) to the Cal Poly Pomona campus. The design aims for a flow rate of 2550 gallons per minute (gal/min). The total pipeline extends 2.34 miles, transitioning from an initial elevation of 348 feet to a final elevation of 365 feet. **Key Details:** 1. **Entrance and Flow Direction:** - At PWRP, a half-open gate valve is located right at the entrance (r/d = 0). 2. **Pipeline Path:** - Along the route, there are smooth bends with vanes (r/d = 8) designed to change the flow direction. 3. **Hydrant Connection:** - Each fire hydrant (represented as FH) includes a tee for creating laterals. 4. **Pressure Requirements:** - A minimum residual pressure of 30 psi is required at the pipeline's end. 5. **Conditions:** - All computations should assume a flow coefficient (α) of 1.0 and a temperature of 15°C. **Task:** Calculate the pipeline velocity, unit head loss, and the residual pressure taking into account both major and minor head losses. **Map Description:** The map shows the detailed pipeline path through the region with key points marked: - **Entrance** at the starting point with indicators of a gate valve. - Multiple **bends** and **fire hydrants (FHH1, FHH2, FHH3)** along the pipeline route. - The total stretch of the pipeline is visually marked along streets and landmarks. **Calculation Options:** - 153.46 psi - 178.32 psi - 193.57 psi - 121.85 psi Use these details for computing the necessary hydraulic parameters and ensure compliance with the specified pressure requirements.
