A horizontal pipe of diameter 0.903 m has a
smooth constriction to a section of diameter
0.5418 m. The density of oil flowing in the
pipe is 821 kg/m3.
If the pressure in the pipe is 8450 N/m2
and in the constricted section is 6337.5 N/m2 ,
what is the rate at which oil is flowing?
Answer in units of m3/s
