Flowing More Water with a Smaller Pipe Scott Brown, EIT

Flowing More Water with a Smaller Pipe Overview Pipe liners are smoother than the existing A smoother pipe means higher velocity A higher velocity means a higher flow Under inlet control conditions, pipe smoothness becomes a minor factor – the end area/geometry become the key factors

Flowing More Water with a Smaller Pipe Manning’s Equation Equation that gives flow estimates based on friction of the pipe material, pipe size, and pipe slope Gives an “apples-to-apples” comparison Applies to a partially or nearly full flowing culvert

Flowing More Water with a Smaller Pipe Manning’s Equation Q = Flow Rate/Discharge - gpm n = Roughness coefficient (Manning’s “n”) d = Pipe Diameter – in. s = Slope – ft/ft

Flowing More Water with a Smaller Pipe Manning’s “n” Coefficient representative of pipe roughness The smaller the number, the smoother the pipe The smoother the pipe, the faster the velocity

Flowing More Water with a Smaller Pipe Manning’s “n” Factors Solid Wall HDPE n = 0.009 – 0.012 Profile Wall HDPE n = 0.012 Concrete n = 0.012 CMP n = 0.024 Multi-Plate n = 0.035

72” CMP PIPE Slope, s= 0.0025 CMP n = 0.024 Q = 51,475.1 gpm Flowing More Water with a Smaller Pipe 72” CMP PIPE Slope, s= 0.0025 CMP n = 0.024 Q = 51,475.1 gpm

63” OD/59.1” ID HDPE SOLID WALL Flowing More Water with a Smaller Pipe 63” OD/59.1” ID HDPE SOLID WALL Slope, s= 0.0025 HDPE Solid Wall n = 0.01* Q = 72,967 gpm *INDOT Hydraulics typically uses 0.01

63” OD/59.1” ID HDPE SOLID WALL Flowing More Water with a Smaller Pipe 72” CMP VS. 63” OD/59.1” ID HDPE SOLID WALL 72” CMP Q = 51,475.10 gpm HDPE Solid Wall Liner Q = 72,967 gpm 72,967/51,475.10 = 1.42 or 142% 42% Increase in flow

Flowing More Water with a Smaller Pipe INLET CONTROL Occurs when the culvert barrel can convey more than it can accept Flow is limited by pipe opening size Manning’s Equation does not apply

Recent INDOT Specification Changes, Oval Liners Darin Duncan, PE

INDOT Standards Committee February 17, 2011 Problem: For the past 4 years, the 725 specification section in the book has been superseded with RSP 725-R-541. Solution: Incorporate the modified 725-R-541 provision into the SS book to replace the existing 725 section

INDOT Standards Committee February 17, 2011 NOTABLE CHANGES: 1. OVAL LINER ADDED

2. TYPE A CERTIFICATION REMOVED INDOT Standards Committee February 17, 2011 NOTABLE CHANGES: 2. TYPE A CERTIFICATION REMOVED

2. TYPE A CERTIFICATION REMOVED – CONT’D http://www.in.gov/indot/2581.htm

2. TYPE A CERTIFICATION REMOVED – CONT’D http://www.in.gov/indot/div/M&T/appmat/appmat.htm

2. TYPE A CERTIFICATION REMOVED – CONT’D http://www.in.gov/indot/div/M&T/appmat/pubs/apl25.pdf QCP Plan is a major factor in getting on the approved list.

3. OVALING MANUFACTURING REQUIREMENTS INDOT Standards Committee February 17, 2011 NOTABLE CHANGES: 3. OVALING MANUFACTURING REQUIREMENTS

4. QUALITY CONTROL CHANGES - INSPECTIONS INDOT Standards Committee February 17, 2011 NOTABLE CHANGES: 4. QUALITY CONTROL CHANGES - INSPECTIONS

5. PIPE CLEANING AND INSPECTION INDOT Standards Committee February 17, 2011 NOTABLE CHANGES: 5. PIPE CLEANING AND INSPECTION

INDOT Standards Committee February 17, 2011 NOTABLE CHANGES: 6. SIZING ALL OF CHART DELETED
