Question

b) The diameters of a pipe are 15 cm and 20 cm at sections 1 and 2 respectively. The velocity of water flowing through the pipe is 4 m/sec at section 1. Determine the discharge through the pipe and also the velocity of flow at section 2.

Answer 1

For a fluid, the density remains the same, hence the discharge will remain constant.

Discharge will be given as;

_____________________________________________________________________

Discharge remains constant, hence;
