A uniform capillary tube of inner radius r is dipped vertically into a beaker filled with water. The viscous force rapidly increases with velocity, attaining a maximum when the ball reaches the terminal velocity. It is giving out 0.74 m3 water per minute through a circular opening of 2 cm radius in its wall. When the vessel is rotated about its own vertical axis, the liquid rises up near the wall. Each subject in each paper has 18 questions each. A sequence of multi-conceptual approach is added in these following illustrations. ExamSIDE.Com. Practice Now.

Assume that the liquid applies a viscous force on the ball that is proportional to the square of its speed v, i.e., Fviscous = –kv2 (k > 0). If the height of the water in the tank remains steady, then this height is, Since the height of the water column is constant, Water inflow rate (Qin) = Water outflow rate (Qout), Q8: A submarine experiences a pressure of 5.05 x106 Pa at depth of d1 in a sea. If the radius of the pipe is 5 cm, the Reynolds number for the flow is of the order (density of water = 1000 kg/m3, coefficient of viscosity of water = 1 mPa s), Reynolds number = {(103 x 2 x 10 x 102)/(10-3 x 3π)}, Q10: The top of a water tank is open to the air and its water level is maintained. in this examination. The weight that can be put on the raft to make it just sink is (10x) kg. Liquids and gases are classified together as fluids because they exhibit the same flow phenomena and have an identical equation of motion. Taught by IITB graduate Akshay Sarode.
