Unformatted text preview: 57:020 Mechanics of Fluids and Transport October 15, 2010 NAME Fluids-ID 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) ...
