• When Froude Number = 1 → the critical condition
• When the Froude Number < 1 → subcritical condition
(tranquil flow)
• When the Froude Number > 1 → supercritical condition
(rapid flow)

Sharp Crested Weir
• Is a thin wall weir
• Thin wall weirs are primarily used to determine the flow of
small streams and channels.
• Cd is the discharge coefficient, specific for each weir and
flow characteristics
• Aeration pipe must be open for Cd determination

Gear Pump
• It is one of the most common types of
pump used in hydraulic fluid power
applications and engine oil pump
systems.
• Their main characteristics are:
Low flow rate
Ability to pump highly viscous fluids
Can generate high pressure head
• Fluid enters the body of the pump at
low pressure and is transferred to the
outlet side at a higher pressure
• Positive displacement

Plunger Pump
• Consists of a piston inside a chamber
which moves in one direction and fluid
is drawn into the chamber.
• The piston then returns as the inlet
valve closes and the outlet valve opens,
forcing the fluid out
• The general pattern expected for the
outlet pressure that of a sine wave
• The pulsation may be smoothed using a
damping system
• Positive displacement
