Quiz 6. A liquid jet of density and area A strikes a block and
splits into two jets, as shown in the figure. All three jets have
the same velocity V. The upper jet exits at angle and area
A, the lower jet turns down at 90 and area (1  )A. Determine the forces (a) Fx and (b) Fy required to support the block
against momentum changes if = 999 kg/m3 (for water), A =
0.1 m2, V = 10 m/s, = 30, and = 0.7. Linear momentum equation: Solution:
(a) From the linear momentum equation in the direction (+3 points)
where . Thus,
(+2 points) (b) From the linear momentum equation in the direction (+3 points)
Thus,
(+2 points) ...
