Fluid Mechanics Quiz

What is the initial speed of water entering the horizontal pipe?

• 2.0 meters per second

• 1.0 meters per second

• 0.5 meters per second

• 0.25 meters per second

How is the final speed of the fluid determined using the continuity equation?

• By adding the initial speed to the cross-sectional area

• By subtracting the initial speed from the final cross-sectional area

• By dividing the initial speed by the cross-sectional area

• By multiplying the initial speed by the ratio of initial to final cross-sectional area
