Pressure due to a liquid is `"________"` of the area of cross-section of containing vessel.

(a) What is meant by the principle of continuity ? Show that velocity of a liquid is inversely proportional to the area of cross-section of a pipe or tube.

Considering a wire of non-uniform cross-section as shown.If the area of cross-section at A is double of the area of cross-section at point B.Ratio of heat energy dissipated in a unit volume per unit time at points A and B is

The volume V of a liquid crossing through a tube is related to the area of cross-section A, velocity v and time t as V alpha A^a v^b t^c which of the following is correct ( given a != 1 )

In this figure, an ideal liquid flows through the tube having uniform area of cross-section and is held in vertical plane. Find the ratio of speed of liquid at A and B and also find the pressure difference between- these points.

The mass of the liquid flowing per second per unit area of cross-section of the tube is proportional to (pressure difference across the ends)^(n) and (average velocity of the liquid)^(m) . Which of the following relations between m and n is correct?

A wire of cross-sectional area A breaks due to its own weight when length of the wire is l. If area of cross-section of the wire is made 3A then maximum length of the wire can be hung without breaking is

When a force of one "________" acts on an area of cross-section 1m ^(2), the pressure exerted is said to be one "___________"

A non viscous liquid of density rho is filled in a tube with A as the area of cross section, as shown in the figure. If the liquid is slightly depressed in one of the arms, the liquid column oscillates with a frequency

When a pressure measuring device is immersed in a liquid, a restoring force of 2 N is exerted by the spring. If the area of cross-section of the pistion is 10 cm^(2) , what pressure does the fluid exert on the piston?

Two gases H_2 and O_2 fuse from two different containers having same pressure and temperature. If the ratio of area of cross section of hole is 1:2 then the ratio of rate of effusion will be
