A horizontal pipe of diameter 0.996 m has a smooth constriction to a section of diameter
0.5976 m . The density of oil flowing in the
pipe is 821 kg/m3
.
If the pressure in the pipe is 7570 N/m2
and in the constricted section is 5677.5 N/m2
,
what is the rate at which oil is flowing?
Answer in units of m3
/s.

Consider motion in one dimension. (the sign of the vector quantities is their direction indicator.) an object moves in the positive x-direction with speed 2.9 m/s for 4.5 s. it stops for 3.8 s and then moves in the negative x direction with speed 2.8 m/s for 4 s. what is the total distance traveled by the object in units of meter? enter a number with two digits behind the decimal point.
