The Coanda effect occurs when a stream of fluid passes over a round object and a low-pressure area is created between the rear half of the object and the fluid stream, causing the fluid to be directed inward rather than outward as would normally be expected. You can demonstrate this at home by putting your finger under the stream of water coming out of the kitchen faucet. When the edge of your finger just penetrates the edge of the water stream, it will deflect toward your finger. For this problem consider a rectangular water sheet of width 1 cm and thickness 2 mm flowing downward with a velocity of 3 m/s. The stream flows over the edge of a cylinder and is turned inward through an angle of 15°. Find the magnitude of the force on the cylinder in the horizontal direction.
