Question 1

Consider the following statements pertaining to a convergent-divergent nozzle flow with Mach number 0.9 at the throat:
1) The flow is subsonic in both the converging and the diverging sections
2) The Mach number at the exit is less than one
3) In the diverging section, the f low is supersonic
4) There is a shock in the diverging section
Which of the above statements are correct?

Question 2

In the below layout of piping, what is the velocity in 200 mm diameter pipe?

Question 3

Which one of the following statements is appropriate for the free surface, the hydraulic gradient line and energy gradient line in an open channel flow?

Question 4

A 12 cm diameter straight pipe is laid at a uniform downgrade and flow rate is maintained such that velocity head in the pipe is 0.5 m. If the pressure in the pipe is observed to be uniform along the length when the down slope of the pipe is 1 in 10, what is the friction factor for the pipe?

Question 5
