A Pitot tube is shown in figure. Wind blows in the direction shown. Air at inlet A is brought to rest, whereas its speed just outside of opening B is unchanged. The U tube contains mercury of density rho_(m) . Find the speed of wind respect to Pitot tube. Neglect the height difference between A and B and take the density of air as rho_(a) .

A pitot tube Fig. is used to determine the air speed of an airplane. It consists of an outer tube with a number of small holes B (four are shown that allow air into the tube, that tube is connected to one arm of a U-tube. The other arm of the U-tube is connected to hole A at the front end of the device, which points in the direction the plane is headed. At A the air becomes stagnant so that v_(A) = 0. At B, however, the speed of the air presumably equals the airspeed v of the plane. (a) Use Bernoulli's equation to show that v = sqrt((2rho gh)/(rho_(air))) where rho is the density of the liquid in the U-tube and his the difference in the liquid levels in that tube. (b) Suppose that the tube contains alcohol and the level difference h is 20.0 cm. What is the plane's speed relative to the air? The density of the air is 1.03 kg//m^(3) and that of alcohol is 810 kg/ m^(3)

In the figure, the cross-sectional area of the smaller tube is a and that of the larger tube is 2a . A block of mass m is kept in the smaller tube having the base area that of the tube. The difference between water levels of the two tubes is

Four identical capillary tubes a,b,c and d are dipped in four beakers containing water with tube a vertically, tube b at 30^(@) tube c at 45^(@) and tube d at 60^(@) inclination with the vertical. Arrange the lengths of water column in the tubes in descending order.
