QUIZ 2 AMK10603

Types of energy when analyzing a pipe flow is

• Kinetic energy

• Chemical energy

• Potential energy

• Flow energy

Equation used to calculate energy loss in laminar flow

• Newton law equation

• Hagen-poiseuille equation

• Darcy law equation

• Moody equation

Causes of major energy loses in enclosed pipeline:

• Change in pipe area

• Change in water path

• Surface roughness

• Water flow direction

Based on the figure, what are the elements that will change if water flow from section 1 to 2 in the pipeline?

• Pressure

• Volume flow rate

• Elevation

• Velocity

The important elements use to determine the value  of 

friction factor (f) for turbulent flow.

• Fluid temperature

• Pipe diameter

• Water viscosity

• Fluid type

Water at 10oC is flowing from point A to point B through the  fabricated section shown in Figure 1 at the rate of 0.40 m3/s.  Given diameter at section A is 250 mm and at section B is 450 mm, calculate the velocity at B.

Based on the figure, if the desired outlet flow velocity is 12 m/s, what is the minimum depth required from water surface to the center of the outlet?
