Water stands upto a height `h` behind the vertical wall of a dam what is the net horizontal force pushing the dam down by the stream if width of the dam is `sigma`? `(rho=` density of water)

Water stands at a depth D behind the vertical upstream face of a dam as shown in the figure. The force exerted on the dam by water per unit width is

Water stands at a depth h behind the vertical face of a dam. It exerts a resultant horizontal force on the dam tendibg to slide it along its foundation and a torque tending to overturn the dam about the point O . Find (a) Horizontal force,(b) torque about O, (c ) the height at which the resultant force would have to act to produce the same torque,l=cross-sectional length and rho= density of water.

Water rises upto a height h in a capillary tube of radius r. What is the network done in this process if the density of water is rho ?

A stream of water flowing horizontally with a speed of 15 ms^(-1) pushes out of a tube of cross sectional area 10^(-2)m^(2) and hits a vertical wall near by what is the force exerted on the wall by the impact of water assuming.that it does not rebound? (Density of water =1000 kg m^(3) )

Figure shows a cross sectional view of a masonry dam whose length perpendiclar to te diagram is 30 m . The depth of the water behind te dam is 10 m . the masonry of which is the dam is constructed has a density of 3000 kg//m^(3) . a. Find the dimensions x and 2x if the weight of the dam is to be 10 times the horizontal force exerted on it by water. b. Check the stability of the dam with respect to its overturning about the edge through point O .
