Homework Statement
A jet of water going through a nozzle is deflected by a flat plate. Get Q, Velocity, Force
The volumetric flow rate of water through the nozzle is 10 Litres in 7 seconds
The water temperature is 20 degrees celcius.
We are using a flat plate so theta = 90 degrees
Velocity coefficient C = 1
Homework Equations
Q (volume flow rate) = volume / time
Velocity = Q / area of nozzle
Force = density of water * Area of nozzle * velocity^2 * (1 - C*cos theta)
The Attempt at a Solution
Density of water at 20 degrees = 998.2 kg/m^3
Q = 0.01 / 7
Q = 1.429 (10^3) m^3/s
I don't know how to get area of nozzle
Using C = 1, theta = 90:
F = 1000 * area of nozzle * V^2
