Consider this figure where diameters D3> D1 > D2 and point C is a pump. Which of the following is true about the flowrate Q2 in pipe D2 and Q2 in pipe Q3? D1 D2 D3 Q2-Q3 Q2

Solution

Q2= Q3

Flow entering any point should be equal to flow leaving the point. Here also flow entering pipe at pipe D1 will be equal to flow in pipe D2 which is equal to follow in pipe D3. The pump will only boosts energy or pressure head of the water. Increase in delivery discharge will automatically increases suction discharge.
