Homework Statement
Water exits the 3-in.-diameter pipe at a velocity of 12 ft/s and is split by the wedge diffuser. Assume water is ideal fluid, that is, incompressible and frictionless. Determine the force the flow exerts on the diffuser. Take θ = 30 ∘
Homework Equations
F = ρAV
The Attempt at a Solution
So what I've seen others do, and what tools I've been given so far in the course, here's the numbers I plugged in, and the equation I used:
ρ = 62.4
A = πr2
R = (3/24) <- 3 inch diameter, and this just eliminates one step in the calculator
V = 12
θ = 15 (half of 30)
F = ρAV(Vcosθ). But I'm getting 426, which isn't correct . . .
