Oil with r = 876 kg/m3 and m = 0.24 kg/m·s is flowing through a 1.5-cm-diameter pipe that discharges into the atmosphere at 88 kPa. The absolute pressure 15 m before the exit is measured to be 135 kPa. Determine the flow rate of oil through the pipe if the pipe is (a) horizontal, (b) inclined 8 upward from the horizontal, and (c) inclined 8 downward from the horizontal.
Fluid Pressure
The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.
Gauge Pressure
Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.

through a 1.5-cm-diameter pipe that discharges into the
atmosphere at 88 kPa. The absolute pressure 15 m before the
exit is measured to be 135 kPa. Determine the flow rate of
oil through the pipe if the pipe is (a) horizontal, (b) inclined 8 upward from the horizontal, and (c) inclined 8 downward
from the horizontal.
