I) explain what is meant by continuity of flow. ii) oil flows through a pipe of internal diameter 100mm at a velocity of 8 m/s. the pipe then splits into two branches. one branch has an internal diameter of 75mm and the fluid is measured to be flowing with a velocity of 5 m/s. if the other branch has an internal diameter of 50mm, at what velocity will the oil flow through this section? b) i) state bernoullis equation and state which form of energy each term represents. ii) a fluid of density 950kg/m3 flows steadily through a tapered tube as shown below. at section 1 the pressure is 250kn/m2 , the velocity is 12 m/s and pipe diameter is 0.1m. if the pipe diameter at section 2 is 0.3m, find the velocity and pressure at section 2
