Q3
The diameters in Fig. 6.3 are 750 mm and 500 mm. At the
larger end the pressure is 650 kPa and the velocity is 2.8 m/s.
Neglecting friction, find the resultant force on the horizontal
conical reducer if water flows (a) to the right; and (b) to the
left. (c) What would happen to the two previous answers if we
did not neglect friction?

4-in-dia jet
Both nozzle jets in Fig. P6.9 discharge horizontally into the
atmosphere with a velocity of 40 fps. The liquid has a
specific weight of 62.4 lb/ft. The axes of the pipe and both
nozzles all lie in a horizontal plane. Find the magnitude and
direction of the resultant force on this double nozzle while
neglecting friction.
