For a fluid with zero viscosity, an increase in the speed of the fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid's potential energy. c. In a steady flow, the sum of kinetic energy, potential energy
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.
3. Which statement(s) related to Bernoulli's Principle is/are true.
a. Bernoulli's principle can be derived from the principle of conservation of
energy.
b. For a fluid with zero viscosity, an increase in the speed of the fluid occurs
simultaneously with a decrease in pressure or a decrease in the fluid's
potential energy.
c. In a steady flow, the sum of kinetic energy, potential energy, and internal
energy remains constant.
d. All of the above.
4. What statement(s) concerning lift is/are true.
a. Air flows faster over the top of the wing decreasing the air pressure.
b. Aircraft’s wing geometry has a large effect on the amount of lift.
c. Newton's laws are typically preferred over the Bernoulli principle to
explain lift.
d. All of the above.
