Students only can take part in this competition. Participants have to submit a small write-up, blue-print along with the model/project. Last date of submission of the project is 15 Apr 2018. The projects/models (along with the write-up, blue-print) which get the prize will be kept by the sponsors of this competition.

A wind tunnel of test cross section of at least 9 inches by 9 inches is to be manufactured using cheap & daily usage items like fan, straws, hardboard, glass/plexiglass, agarbatti (for smoke generation) etc.
A balance using lever principle or any other method should be able to estimate the amount of drag, lift (& hence CL, CD) etc. on the various models of aerofoils, aerodynamic or other bodies.
A flow visualisation facility like smoke, woolen tufts, dry ice …
1. What are the SI & CGS
units of viscosity & kinematic viscosity? What is the relation between the
SI & CGS unit of viscosity? What is the value of viscosity of air &
water at 288 K temperature?
2. (a)Define bulk modulus of elasticity
without using any formula? (b) Bulk modulus of elasticity of water is 2000000
kN/m2. A pressure of 10 bar
is applied on water having volume of 2m3. Find the change in volume of water in m3. 3. Find
the flux of velocity having the components as 9x, -3y and 0 along the x, y and
z axes respectively over the closed surface of the sphere given by x2
+ y2 + z2 = 9. 4. A flow field is given by u = ay, v = bz & w =cx. Determine
whether the flow is rotational or irrorational. 5. The clearance space between
a shaft and a concentric sleeve has been filled with a Newtonian fluid. The sleeve attains a speed of 600 mm/s when a force of 600N is applied to it
parallel to the shaft. What force is needed if it is desired to move…
