A liquid of density rho is filled in a vessel up to height H and a hole of cross section area A is made at a depth h below the free surface of liquid. The speed of liquid coming out of the hole is independent of

A stream of a liquid of density p flowin horizontally with speed v rushes out of a tube of radius r and hits a verticla wall nearly normally. Assumi g that the liquid does not rebound from the wall, the force exerted o the wall by the impact of the liquid is given by

Length of a horizontal arm of U-tube is L and ends of both the vertical arms are open to atompsheric pressure P_(0) , A liquid of density rho is poured in the tube such that liquid just fills the horizontal part of the tube as shown in figure . Now one end of the opened ends is sealed and the tube is then rotated about a vertical axis passing through the other vertical arm with angular speed omega_(0) . if length of each vertical arm is a and in the sealed end liquid rises to a height y, find pressure in the sealed tube during rotation.

A cylindrical tube with a frictionless piston ends in a small hole of area of cross–section 2xx10^(-6)m^(2) , which is very small as compared to the area of cross-section of the tube. The tube is filled with a liquid of density 10^(4)kg//m^(3) . The tube is held horizontal and the piston is pushed at a constant speed so that liquid comes out of the hole at a constant rate 'Q' m^(3)//s . No liquid leaks around the piston. The material of the tube can bear a maximum pressure 6xx10^(5) Pa. The maximum possible value of Q so that the tube does not break is __________ xx10^(-5)m^(3)//s . [Atmospheric pressure = 10^(5) Pa]

A horizontal jet of water coming out of a pipe of area of cross-section 20cm^(2) hits a vertical wall with a velocity of 10ms^(-1) and rebounds with the same speed. The force exerted by water on the wall is .

Artificial satellites go round the earth in their respective orbits. Astronauts are able to float in side the satellite. Inside space of the satellite could be treated as gravity free space. If a beaker filled with a liquid upto height h having a small hole in the bottom is placed in such a satellite, you will wonder te liquid does not come out of the hole. You have to squeeze or force the liquid to come out. suppose a constant pressure p is applied on the liquid through piston to force it out through the hole. Out side pressure could be neglected in comparison with p Cross-sectional area of beaker is too greater than that of hole (Agtgta)
