A pipe 300m long has a slope of 1:100 and converts from a 1-m diameter at its upper end, where the pressure is 6.87x10ʻkg/m-sec? (68.7kN/m²). To 0.5m at its lower end. If the water flows at a rate of 5400lit/min, determine the pressure at the lower end. Assume the energy loss due to friction is negligible.

Along a 50-m pipeline, there is a half-open globe valve (K = 10), four 90-degree smooth bends (K = 0.45), and six 45-degree elbows (K = 0.15). Ignoring the major head loss, what will be the pressure drop in this pipe if the flow velocity is 1 m/s? Fluid is water: Specific weight = 9810 N/m³. O 0 kPa O 6.35 kPa O 13.81 kPa O 21.67 kPa
