Question 3 (2 marks) (2 marks) (2 marks) (2 marks) (2 marks) Determine the headloss (hL) due to friction in a 1.54 m diameter, 366 m long tubing with the flowrate (Q) 2 m3/s using both Manning's equation (with n = 0.0196) and the Hazen-Williams equation (with C = 100). Given the hydraulic radius (R) is 0.385 m. Determine the following: a) Area (A) b) Uniform flow section factor AR2/3 c) Headloss using Manning equation (in S.I. unit) d) Headloss using Hazen-Williams equation (in S.I. unit)
