When 0.1 m³/s water flows through a pipe of area 0.25 m², which later reduces to 0.1 m², what is the velocity of flow in the reduced pipe?

QUESTION 5 Q2. Two water pipelines converge into one line of 2.5m diameter. a). What is the velocity of water flowing in the converged line if the discharges and diameters of the converging lines are 1 m3/s with an 800mm pipe and 0.5 m³/s with a 500mm pipe? (m/s) b). What is the mass flowrate under these conditions? (kg/s) c). What percentage change in velocity would there be in the converged pipe if the diameter of the pipe was reduced by 20%? Take the density of water to be 103 kg/m3. Part a). is denoted Q5, part b). as Q6 and part c). as Q7

5. A smooth plastic 10-m long garden hose with an inside diameter of 20 mm is used to drain a wading pool as shown below. What is the flow rate from the pool? 0.2 m ▼ 0.23 m
