4. • Continuity equation is the flow rate has the
same value (fluid isn’t appearing or
disappearing) at every position along a tube
that has a single entry and a single exit for fluid
Definition
flow.
• This principle is known as the conservation of
mass.
• This equation for the ideal fluid
(incompressible, nonviscous and has steady
flow).
7. Formula
Q= Av = V/t
Where :
Q = rate (m3/s)
A = Area (m2)
v = Velocity (m/s)
V = Volume (m3)
t = time (s)
8. The velocity water of The river with different
garden hose before we area which change
hold it and after we
along their length
hold it
Application in daily life
Water gun
Volumetric pipette
Etc..
13. Fluid flows in the pipe that has differrent radius, radius and
velocity of position A are 3 cm and 8m/s, how much the
velocity of water of position B and C, if radius of B and C are 1
cm and 5 cm?
Known : rA= 3cm → 3 x 10-2 m2 vA= 8m/s
rB= 1 cm → 1 x 10-2 m2 rC= 5 cm → 5x 10-2 m2
Question : vB and vC?
Answer :
Problem Sample
14. • Continuity Equation says fluid speeds up going
to smaller opening, slows down going to larger
opening
• Velocity of fluid which is incompresible
Conclusion
Inverse with area of the pipe where the fluids
are flowing
