Answer 1

1 Ratio of inertial to viscous forces- J Re

2 Responsible for the capillary rise and fall - H (sigma s)

3 Pressures constant along a streamline - C couette flow

4 The model and prototype have the same -

time scale ratio. - A kinamatic similarity

5 Flow driven by a pressure gradient - L poiseuilly flow

6 Distance that the boundary layer deflects streamlines to preserve mass flow - M delta plaus(x)

7 Heads constant along a streamline - K pressure , velocity and elevation

8 Streak line - G curved formed by particle moving in time

9 Path line -B curved formed by particles moving in time

10 The model and prototype have the same force scale.

11 A sufficiently strong adverse pressure

gradient can cause this phenomenon -E separated flow

12 Downstream disturbance in the flow after a static or moving body - I WakeWake
