Question 1
Which of the following is correct statement?
Question 2
Statement (I): The turbulent boundary layer will have more steep velocity gradients at the boundary than the laminar boundary layer.
Statement (II): The velocity distribution is parabolic in turbulent boundary layer.
Question 3
A pipe of diameter 1.5 m is required to transport an oil of relative density 0.9 and kinematic viscosity =3 x 10-2 stokes at a rate of 3.0m3/s. If a 15 cm diameter pipe with water at 200C (v=0.01 stokes) is used to model the above flow, then the discharge in the model is_______m3/s.
Question 4
Two reservoirs are connected by a pipe of 200mm diameter for a distance of about 4.5km. Considering the friction coefficient as 0.01 and the difference in water level with the reservoirs as 6.25m, compute the velocity in the pipe (in m/s) considering the system to exhibit exit and entry losses.
Question 5
The following statements are related to a laminar flow occurring in a circular conduit. Which one of the following statement is INCORRECT?
