Introduction to Fluid Mechanics

What is a fluid?

• A fluid is a substance that can flow and take the shape of its container.

• A fluid is a solid that maintains its shape.

• A fluid is a gas that cannot flow.

• A fluid is a type of rock that is found underground.

What is hydrostatic pressure?

• Hydrostatic pressure is the pressure exerted by a fluid at rest due to gravity.

• Hydrostatic pressure is the pressure caused by moving fluids.

• Hydrostatic pressure is the pressure experienced by objects in motion.

• Hydrostatic pressure is the pressure exerted by a gas in a closed container.

Can you explain Bernoulli's Equation?

• Bernoulli's Equation only applies to compressible fluids.

• Bernoulli's Equation is used to calculate temperature changes in fluids.

• Bernoulli's Equation states that pressure is always constant in fluid flow.

• Bernoulli's Equation states that P + 0.5ρv² + ρgh = constant for incompressible, non-viscous fluid flow.

What are the types of fluid flow?

• Centrifugal flow

• Viscous flow

• Laminar flow, Turbulent flow, Compressible flow, Incompressible flow

• Static flow

What is viscosity?

• Viscosity is the temperature at which a fluid boils.

• Viscosity is the density of a fluid.

• Viscosity is the measure of a fluid's resistance to flow.

• Viscosity is the measure of a fluid's color.

What is mass transfer in fluids?

• The measurement of fluid density in a given volume.

• The chemical reaction that occurs in fluids during mixing.

• Mass transfer in fluids is the movement of mass from one location to another within a fluid medium.

• The process of heating fluids to increase their temperature.

What is head loss in fluid systems?

• Head loss is the increase in fluid pressure due to elevation changes.

• Head loss is the measurement of fluid velocity in a pipe.

• Head loss is the reduction in fluid energy due to friction and turbulence in a system.

• Head loss refers to the total energy gained by a fluid in a system.

What is friction loss?

• Friction loss is the gain of pressure in a fluid flowing through a pipe.

• Friction loss is the measurement of fluid density in a pipe.

• Friction loss is the pressure loss due to friction in a fluid flowing through a pipe.

• Friction loss refers to the increase in temperature of a fluid due to friction.

How do we measure fluid flow?

• Fluid flow is measured with pressure gauges.

• Fluid flow is measured using thermometers.

• Fluid flow is measured using flow meters.

• Fluid flow is measured by counting droplets.

What are some phenomena in fluid flow?

• static pressure

• thermal conductivity

• electromagnetic flow

• Some phenomena in fluid flow include laminar flow, turbulent flow, viscosity, boundary layers, and flow separation.
