Problem Statement

 * This video has good explanation what is cavitation and what cause it. Want to measure water velocity as part of creating cavitation. Need to draw (sketchup tutorial) turbine, and figure out how to produce a rotating shaft that protrudes from a pipe so can measure water speed. Explore relationship between water velocity and water pressure in a pipe.

Relationship between velocity and pressure

 * Bernoulli's Principle - Following this principle,a fundamental law of fluids in motion, when flow speed increases, pressure decreases and vice versa.
 * Study more about this principle - http://en.wikipedia.org/wiki/Bernoulli's_principle


 * Continuity equation - When a fluid is in motion, it must move in such a way that mass is conserved.
 * Learn more about this equation - http://en.wikipedia.org/wiki/Continuity_equation

[Target Audience]

 * People who want to make a turbine on SketchUp.

[Starting Point]

 * Google Sketchup.

[Replication Goal]

 * Draw blades of a turbine on SketchUp.

[Procedure for making a turbine on SketchUp]

 * (1) Select "polygon" and set its size.
 * (2) Set its radius.
 * (3) Using "push/pull" and make a solid body.
 * (4) Draw an orientation line using "Line."


 * (5) Draw guide lines for blades.
 * (6) Using "Arc," draw two arc lines.
 * (7) Erase all the guide lines using "Eraser."
 * (8) Once again, use "push/pull" and make a blade.


 * (9) Make the whole thing as a component.
 * (10) Click "create"
 * (11) Find its center.
 * (12) Hold control button and paste another blade.


 * (13) Type 23x in the little box on the left down side so that the total number of the blades will be 24.
 * (14) Click the right button of your mouse and edit components.
 * (15) Using "Rotate" tool, you can change its angle.
 * (16) Finished.

[Target Audience]

 * People who want to make a turbine on SketchUp.

[Starting Point]

 * Google Sketchup.

[Replication Goal]

 * Draw a hub cap of a turbine on SketchUp.

[Procedure for making a turbine on SketchUp]

 * (1) Find the center of the body and draw a line using "Line" tool.
 * (2) Make a rectangle besides the body using "Rectangle" tool.
 * (3) Draw an arc line on the rectangle using "Arc" tool.
 * (4) Put the rectangle onto the body with blades.


 * (5) Using "Rotation" toll make it going through the center.
 * (6) Connect the midpoint in component.
 * (7) Using "Eraser" tool leave only half of the hub drawing.
 * (8) Draw a circle on the center of the body.


 * (9) Using "Follow me" tool, select the half of the hub and follow the circle.
 * (10) Finished.
