A pipe of diameter D is connected to a water tank of large cross-sectional area in which water is maintained at a height H as shown in the figure. A nozzle of diameter ‘d’ fitted at the end of the pipe discharges water into the atmosphere. Find the flow rate, given that the density of water is p. Also find pressure at point C. (P_(0) is the atmosoheric pressure)

A long cylindrical tank of cross-sectional area 0.5m^(2) is filled with water. It has a small hole at a height 50cm from the bottom. A movable piston of cross-sectional area almost equal to 0.5m^(2) is fitted on the top of the tank such that it can slide in the tank freely. A load of 20 kg is applied on the top of the water by piston, as shown in the figure. Calculate the speed of the water jet with which it hits the surface when piston is 1m above the bottom. (Ignore the mass of the piston)

Two soap bubbles are stuck together with an intermediate film separating them. Compute the radius of curvature of this film given that the radii of the bubbles in this arrangement are r_(1) and r_(2) respectively. If r_(1) gt r_(2) state clearly which way the intermediate film will bulge. For the case when r_(1)=r_(2)=2cm calculate he radius of the bubble formed by bursting the intermediate film. The volume of a spherical dome of radius R and height h is pib^(2)(3R-b)//3.

A horizontally oriented bent thin tube ABC of length 1.4 m rotates with a constant angular velocity omega about a stationary vertical axis OO’ passing through the end A as shown in figure. The portion BC of tube is parallel to OO’ and its length is equal 0.4 m. At t=0, AB part of tube is filled with an ideal fluid. The end A of tube is open, the closed end C has a very small orifice. Find the maximum height reached by fluid relative to end C.
