STATEMENT-1: The stream of water flowing at high speed from a garden hose pipe tends to spread like a fountain when held vertically up, but tends to narrow down when held vertically down. STATEMENT-2: In any steady flow of an incompressible fluid, the volume flow rate of the fluid remains constant.

The flow rate of water from a tap of diameter 1.25cm is 0.36L//min . The coefficient of viscosity of water is 10^(-3) Pas. After sometimes the flow rate is increased to 3L/min. Characterise the flow for both the flow rates.
