A horizontal tube of uniform cross-sectional area `A` is bent in the form of `U` as shown in figure. If the liquid of density `rho` enters and leaves the tube with velcity v, then the extermal force `F` requried to hold the bend stationary is

The figure shown a pipe of uniform cross-section inclined in a vertical plane. A U-tube manometer is connected between the point A and B. If the liquid of density rho_(0) flows with velocity v_(0) in the pipe. Then the reading h of the manometer is

Fig, shows a U-tube of uniform cross-sectional area A accelerated with acceleration a as shown. If d is the seperation between the limbs. Then the difference in the levels of the liquid in the U-tube is

The figure represents a U-tube of uniform cross-section filled with two immiscible liquids. One is water with density rho_(w) and the other liquid is of density rho . The liquid interface lies 2 cm above the base. The relation between rho and rho_(w) is .

one end of a U-tube of uniform bore (area A) containing mercury is connected to a suction pump. Because of it the level of liquid of density rho falls in one limb. When the pump is removed, the restoring force in the other limb is:

Water (density rho ) is flowing through the uniform tube of cross-sectional area A with a constant speed v as shown in the figure. Find the magnitude of force exerted by the water on the curved corner of the tube is (neglect viscous forces)
