Does pressure is the same in all direction at definite depth?

Yes, pressure is the same in all directions at a definite depth.

Pressure varies depending on the type of fluid at depth.

Pressure is only uniform in one direction at depth.

Pressure increases with depth in all directions.

What happen to the pressure in the liquid if the liquid density decrease?

The pressure in the liquid decreases.

The pressure in the liquid fluctuates randomly.

The pressure in the liquid increases.

The pressure in the liquid remains the same.

Which of the following is the formula to calculate absolute pressure?

Absolute Pressure = Gauge Pressure + Atmospheric Pressure

Absolute Pressure = Atmospheric Pressure - Gauge Pressure

Absolute Pressure = Gauge Pressure * Atmospheric Pressure

Absolute Pressure = Gauge Pressure - Atmospheric Pressure

Which of the following is the definition for Pascal's Principle?

Pressure applied to a confined fluid is transmitted equally in all directions.

Pressure applied to a fluid is absorbed by the fluid.

A confined fluid cannot transmit pressure.

Pressure in a fluid decreases with depth.

Which of the following is the application of Pascal's Principle?

Hydraulic systems (e.g., hydraulic lifts, brakes)

Which of the following defines the best Archimedes' Principle?

An object submerged in a fluid experiences a buoyant force equal to the weight of the fluid displaced.

An object floats if it is denser than the fluid it is in.

Buoyant force is always greater than the weight of the object.

An object in a vacuum experiences no buoyant force.

Which of the following equation can be used to calculate bouyant force?

F_b = ρ_fluid * V_displaced * g

F_b = ρ_fluid * V_submerged * g

What is fluid laminar flow?

Fluid laminar flow is a type of flow where fluid moves in parallel layers with no disruption between them.

Fluid laminar flow is characterized by turbulent mixing of layers.

Fluid laminar flow occurs only at high velocities.

Fluid laminar flow involves random movement of particles.

What is Bernoullis's Equation?

Bernoulli's Equation: P + 0.5ρv² + ρgh = constant, where P is pressure, ρ is fluid density, v is fluid velocity, g is acceleration due to gravity, and h is height.

What happen to pressure if the air speed drop?

Pressure increases when air speed drops.

Pressure remains constant regardless of air speed changes.

Pressure fluctuates randomly with air speed changes.

Pressure decreases when air speed drops.

What is fluid viscosity?

Fluid viscosity is the measure of a fluid's resistance to flow.

Fluid viscosity is the color of a fluid.

Fluid viscosity is the density of a fluid.

Fluid viscosity is the temperature of a fluid.

What is liquid surface tension?

Liquid surface tension is the force that causes the surface of a liquid to contract and resist external force, due to cohesive interactions among liquid molecules.

Liquid surface tension is the speed at which a liquid evaporates.

Liquid surface tension is the weight of a liquid per unit area.

Liquid surface tension is the temperature at which a liquid boils.
