Questions 1–2 of 2. Imported answers require independent review unless marked reviewed.

Which of the following statements is/are TRUE?

Your answerSelect all correct options. You can choose more than one.

The thickness of a turbulent boundary layer on a flat plate kept parallel to the flow direction is proportional to the square root of the distance from the leading edge

If the streamlines and equipotential lines of a source are interchanged with each other, the resulting flow will be a sink

For a curved surface immersed in a stationary liquid, the vertical component of the force on the curved surface is equal to the weight of the liquid above it

For flow through circular pipes, the momentum correction factor for laminar flow is larger than that for turbulent flow
