A horizontal pipe of diameter 1.03 m has a
smooth constriction to a section of diameter
0.618 m. The density of oil flowing in the pipe
is 821 kg/m³.
If the pressure in the pipe is 9020 N/m² and
in the constricted section is 6765 N/m², what
is the rate at which oil is flowing?
Answer in units of m³/s.
