Water at 15°c (rho = 999.1 kg/m³ and μ = 1.138 × 10⁻³ kg/m·s) is flowing steadily in a 29-m-long and 6-cm-diameter horizontal pipe made of stainless steel at a rate of 10 l/s. determine the pressure drop, the head loss, and the pumping power requirement to overcome this pressure drop. the roughness of stainless steel is 0.002 mm.
