In the context of a sewer system, your objective is to find the optimal slope (SS) of a pipe to meet a design flow rate (QdQd​) and a maximum allowed flow depth percentage (y/Dy/D). Utilize the flow velocity equation: V = -2 * SQRT(8 * g * R * S) * LOG10((ks / (14.8 * R)) + (2.51 * μ / (4 * ρ * R * SQRT(8 * g * R * S))) Given:  Design flow rate (QdQd​): 4.12 m³/s Pipe diameter (DD): 1 m Pipe roughness (ksks): 1.50E-06 m Maximum flow depth percentage (y/Dy/D): 85% Fluid density (ρρ): 999.1 kg/m³ Fluid viscosity (μμ): 1.14E-03 Pa·s Acceleration due to gravity (gg): 9.81 m/s²

Question

In the context of a sewer system, your objective is to find the optimal slope (SS) of a pipe to meet a design flow rate (QdQd​) and a maximum allowed flow depth percentage (y/Dy/D). Utilize the flow velocity equation: V = -2 * SQRT(8 * g * R * S) * LOG10((ks / (14.8 * R)) + (2.51 * μ / (4 * ρ * R * SQRT(8 * g * R * S)))

Given: 

  • Design flow rate (QdQd​): 4.12 m³/s
  • Pipe diameter (DD): 1 m
  • Pipe roughness (ksks): 1.50E-06 m
  • Maximum flow depth percentage (y/Dy/D): 85%
  • Fluid density (ρρ): 999.1 kg/m³
  • Fluid viscosity (μμ): 1.14E-03 Pa·s
  • Acceleration due to gravity (gg): 9.81 m/s²
