Water is used as the manometric liquid in a pitot tube mounted in an aircraft to measure air speed. If the maximum difference in height between the liquid columns is `0.1 m,` what is the maximum air speed that can be measured? Density of air `d_("dir")=1.3kg//m^(3)`

If a room has dimensions 3m x 4m x 5m, what is the mass of air in the room if density of air at NTP is 1.3kg/m^(3)

What is the mass of air in a room measuring 10.0 m x 5.2 m x 2.5 m, if the density of air is 1.3 kg//m^3 ?

What is the mass of air in a room of dimensions 3mxx4mxx5m , when the density of air is 1.3 kg m^(-3) ?

A point tube is mounted on an aeroplane wing to measure the speed of the plane. The tube contains alcohol and shows a level difference of 40 cm. What is the speed of the plane reative to air ? (sp. Gr. Of alcohol = 0.8 and density of air = 1 kg m^(-3) ).

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)

A pitot tube (see Problem 46) on a high-altitude aircraft measures a differential pressure of 150 Pa. What is the air craft's airspeed if the density of the air is 0.031 kg//m^(3) ?
