4 cards from this section. Quick, good the night before a test.
What aligns with the free surface in an open channel flow?
Think about the characteristics of an open flow.
What does the energy gradient line include?
Consider what influences energy in a fluid.
What does the hydraulic gradient line represent in an open channel?
Consider the definition and characteristics of open channel flow.
True or False: Energy losses in fluid systems only pertain to heat.
Think about what types of energy loss occur in real systems.
Calculate the power output of a turbine where the pressure drop from point 1 to point 2 is 4000 N/m², flow rate is 0.1 m³/s, and efficiency is 85%.
Remember the formula for power, working through the units carefully.
Analyze a situation where fluid flows through a pipe with a sudden enlargement (200 mm to 400 mm) and a rise in pressure head of 0.01 m. How does this affect flow rate?
Keep in mind the relationship of velocity to diameter in the continuity equation.
