At a given point in a pipe (diameter D) the gauge pressure ofthe fluid,with density ρ kg/m³ and viscosity µ Pa.s, inside the pipe, is PPa. How many meters of pipethe pressure will reach half the pressure P Pa for a flow rate Qm³/s (disregard head lossesminors)? (To resolve this issue, assign values ​​to D, P, ρ, µ, andQ so that the flowis turbulent, and assume that the pipeline is made of castiron).
