Fluid Dynamics and Energy Concepts

What is the velocity of the fluid entering the pipe referred to as?

• v2

• v1

• A1

• P1

Which principle states that energy input equals energy output in a closed system?

• Conservation of Energy

• Law of Thermodynamics

• Bernoulli's Principle

• Newton's First Law

What is the formula for work done in terms of force and distance?

• Work = Force - Distance

• Work = Force x Distance

• Work = Force / Distance

• Work = Force + Distance

How is the volume of fluid related to mass and density?

• Volume = Mass + Density

• Volume = Mass x Density

• Volume = Mass / Density

• Volume = Density / Mass

What remains constant in the system regarding mass?

• Input mass equals output mass

• Mass is not constant

• Output mass is greater than input mass

• Input mass is greater than output mass

What is the potential energy of a system dependent on?

• Pressure and area

• Mass and velocity

• Mass and height

• Velocity and height

What is the formula for kinetic energy?

• KE = mv^2

• KE = mv

• KE = 2mv^2

• KE = mv^2 / 2

What does the term 'mgh' represent in the context of energy?

• Potential energy

• Kinetic energy

• Work done

• Pressure energy

What is the relationship between input and output energy in the system?

• Input energy is unrelated to output energy

• Input energy equals output energy

• Input energy is more than output energy

• Input energy is less than output energy

What is the significance of the term 'P1' in the energy equation?

• Output pressure

• Input pressure

• Output velocity

• Input velocity
