14. Activities

15. Properties of a fluid
 Used to determine the behaviour of a fluid in
fluid mechanics. They are,
 Density
 Viscosity
 Surface Tension
 Capillary Action
 Specific Weight
 Specific Gravity

16.  Think and Say?

17. Is Stone less or more dense than
water?
Less Dense
Sink
If you drop a piece of wood into
water will it sink or float?
More Dense
Float

18. Surface tension of fluids

19. CapillaryAction of fluids

20. Models
 Designing Model of Hydraulic devices like
Hydraulic lift , crane, coupling
 Making modal of a simple displacement pump
using PVC piping.
 Design the model for Open Channel Flow as
Rectangular and Trapezoidal section
 Design the notches for most economical
sections

21. Activities Planned
 Find the losses in pipes due to Sudden
Enlargement, Sudden Contraction and Sudden
Bending for the given pipes
 Design the suitable pump for given
configuration of pipes for required discharge
 Design the most economical section model
and take a flow measurements by using
various types of notches

22. Industrial visits
 Visit to aquatex pump industries in Coimbatore
 Visit to Fluid Control Research Institute,
Kanjikode West, Palakkad, under ministry of
heavy industries & public enterprises, govt of
India,
 Visit to dams , Parambikulam – Aliyar
