Q9.A reducing bend is fitted in a horizontal section of freshwater system as shown in Fig Q9. It turns the flow through an angle of 90^o anticlockwise to the direction of flow.

The system pressure and fluid velocity at inlet are 8 bar and 1.5 m/s respectively.

The bend has diameters of 300 mm at inlet and 150 mm at outlet.

The friction loss in the bend may be ignored.

Calculate EACH of the following:

(a) The system pressure at the bend outlet; (4)

(b) The forces acting in the X and Y directions due to the charge in diameter; (3)

(c) The forces acting in X and Y directions due to the change in momentum; (3)

(d) The magnitude of the resultant force acting on the bend; (4)

(e) The direction of the resultant force. (2)
