Flow measurement_Sec 1_ Morning section

The Bernoulli's equation is based on the assumption that

• Velocity is uniform across any cross-section of the pipe

• There is no loss of energy of the liquid flowing

• Flow is steady

• All of the above

The Bernoulli's equation refers to conservation of

• Linear momentum

• Mass

• Energy

• Angular momentum

In the question: H_T = P/(ρ g) + V²/(2g) + Z, H_T is

• Velocity head

• Pressure head

• Total head

• Elevation head

In the question: H_T = P/(ρ g) + V²/(2g) + Z, P/(ρ g) is

• Total head

• Pressure head

• Elevation head

• Velocity headf

In the question: H_T = P/(ρ g) + V²/(2g) + Z, V²/(2g) is

• Elevation head

• Pressure head

• Velocity head

• Total head

In the question: H_T = P/(ρ g) + V²/(2g) + Z, Z is

• Total head

• Elevation head

• Velocity head

• Pressure head

What does head mean in hydraulic system?

• Fluid total energy per unit weight

• Fluid pressure per specific weight

• Fluid velocity per mass

• Fluid height above the level
