Water flows through a pipe which narrows from a cross-sectional area A1 to a cross-sectional area A2 which is one-third of A1. The flow speed of the water that crosses through the cross-section of area A2 is a. nine times the flow speed flowing through A1. b. three times the flow speed flowing through A1. c. equal to the flow speed flowing through A1. d. one-third of the flow speed flowing through A1.
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.
Water flows through a pipe which narrows from a cross-sectional area A1 to a cross-sectional area A2 which is one-third of A1. The flow speed of the water that crosses through the cross-section of area A2 is
a. nine times the flow speed flowing through A1.
b. three times the flow speed flowing through A1.
c. equal to the flow speed flowing through A1.
d. one-third of the flow speed flowing through A1.
