Question

According to the Bernoulli equation which of the following is true:

A.)Pressure on the upper surface of the wing is higher than the lower surface of the wing
B.)The higher the static pressure the higher the dynamic pressure
C.)When upper wing pressure is exactly the same as lower wing pressure (everywhere along the wing) there is no lift
D.)Static pressure is analogous to Kinetic Energy

Answer 1

According to the Bernoulli equation, the pressure on the upper surface of the wing is lower than the pressure on the lower surface of the wing. When the pressure on the upper surface of the wing is the same as the pressure on the lower surface of the wing, there is no lift. Static pressure is not directly analogous to kinetic energy.

Step-by-step explanation:

According to the Bernoulli equation, the pressure on the upper surface of the wing is lower than the pressure on the lower surface of the wing. This is because the air flows faster over the top of the wing, which reduces the pressure. The difference in pressure creates lift.

The higher the dynamic pressure, the higher the static pressure. Dynamic pressure is related to the speed of the fluid flow, while static pressure refers to the pressure when the fluid is not in motion.

When the pressure on the upper surface of the wing is the same as the pressure on the lower surface of the wing (everywhere along the wing), there is no lift. Lift is generated when there is a difference in pressure between the upper and lower surfaces of the wing.

Static pressure is not directly analogous to kinetic energy. Static pressure is the pressure exerted by a fluid at rest, while kinetic energy is the energy of an object due to its motion.
