(a) A horizontal pipe of diameter 10 cm carries crude oil from A to C as shown in Figure 4. At a point B, midway between A and C, oil leaks at a volume flow rate of QL . The pressure drop per unit length along AB is 640 Pa/m and along BC is 600 Pa/m. Determine the leakage flow rate QL . The density of oil is 800 kg/m3 and its dynamic viscosity is 0.1 N.s/ m2 . You may assume that the flow is laminar.
Summary: Both problem is solved using Darcy- Weisbach equation.The length of pipe in question-3b will be 120m.
