Question 1
The thickness of the laminar boundary layer on a flat plate at a point A is 2 cm and at a point B, lm downstream of A, is 3 cm. What is the distance of A from the leading edge of the plate?
Question 2
The flow of water (mass density = 1000 kg/m3 and kinematic viscosity = 10–6 m2/s) in a commercial pipe, having equivalent roughness ks as 0.12 mm, yields an average shear stress at the pipe boundary = 600 N/m2. The value of 
being the thickness of laminar sub–layer) for this pipe is
being the thickness of laminar sub–layer) for this pipe is Question 3
How does the head loss in turbulent flow in pipe vary?
Question 4
For laminar flow over a flat plate, the thickness of the boundary layer at a distance from the leading edge is found to be 5 mm. The thickness of the boundary layer at a downstream section, which is at twice the distance of the previous section from the leading edge, will be
Question 5
For laminar flow through a pipe, the discharge vanes
Question 6
A rectangular open channel of width 4.5 m is carrying a discharge of 100 m3/sec. The critical depth of the channel is
Question 7
A flat plate of 0.15 m2 is pulled at 20 cm/s relative to another plate. fixed at a distance of 0.02 cm from it with a fluid having J.1 = 0.0014 N-s/m2 separating them. What is the power required to maintain the motion?
Question 8
A rectangular pontoon has a width of 6 m, a length of 12 m and a draught of 1.5 m in fresh water (density = 1000 kg/m3). It's draught in sea water having density of 1025 kg/m3 is
Question 9
A 2-D flow field is defined as 
The equation of streamline passing through the point (1,1) is
The equation of streamline passing through the point (1,1) is Question 10
A 25 cm long prismatic homogeneous solid floats in water with its axis vertical and 10 cm projecting above water surface. If the same solid floats in some oil with its axis vertical and 5 cm projecting above the liquid surface, what is the specific gravity of the oil?
