1) A rectangular channel 5 m wide carries a discharge of 10 m^3/s at a uniform depth of 3 m. The channel is running on a slope of 0.0025 m/m. Estimate wall shear stress and friction velocity. Assume the density of flowing water as 1000 kg/m^3.

2) A horizontal pipe 0.3 m in diameter has an available pressure drop of 100N/m^2 to drive a flow rate of 0.5 m^3/s across a length of 100m. What shear stress will be developed on the pipe boundary by this flow condition?
