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.

A

`(rhoQ^(2)l)/(pir^(2))`

B

`(rhoQ^(2)l)/(pir)`

C

`(rhoQ^(2)l)/(r^(2))`

D
