Water flows out of a big tank along a tube bent at right angles, the inside of the tube is of radius `r`. The length of the horizontal portion is `l`. The rate of water flow is `Q`. Find the moment of reaction forces of flowing water, acting on the tube walls relative to point `O`.

Water flows out of a big tank along a tube bent at right angles, the inside radius of the tube is equal to r (figure). The length of the horizontal section of the tube is equal to l . The water flow rate is Q litres per second. Find the moment of reaction forces of flowing water, acting on the tube's walls, relative to the point O.

Water flows out of a big tank along a tube bent at right angles, the inside radius of the tube is equal to r=0.50cm (figure). The length of the horizontal section of the tube is equal to l=22cm . The water flow rate is Q=0.50 litres per second. Find the moment of reaction forces of flowing water, acting on the tube's walls, relative to the point O.

Water flows out of a big tank along a horizontal tube Ab of length L and radius R and bends at right angle at the other end as shown in the figure. Find moment of force exerted by water on the tube about the end A (Assume that the radius of the tube is small )

Water is flowing through a tube of radius r with a speed v. If this tube is joined to another tube of radius r/2, what is the speed of water in the second tube?

Water is flowing through a tube of radius r with a speed v. If this tube is joined to another tube of radius r/2, what is the speed of water in the second tube?

Water flows with a velocity V in a tube of diameter d and the rate of flow is Q. another tube of diameter 2d is coupled to the first one. The velocity of water flowing out and rate of flow in the second tube are respectively.

A fluid is flowing through a tube of length L. The radius of the tube is r and the velocity of the fluid is v. If the radius of the tube is increased to 2r, then what will be the new velocity?
