1. What is a streamline? Streamline is a line through fluid flow, such that velocity vectors
are tangential to it at all points.
2. What are the different com- local acceleration (dv/dt), convective acceleration V-> *
ponents of accelerations? (dv->/ds), and centripetal acceleration (v^2 -> / R)
3. What is the basic assumption Friction or viscous forces are ignored
involved in the Euler equa-
tion?
4. What is the relationship of The pressure at the center of the rotating fluid is always lower
pressure in the rotating fluid
at the center of the fluid and
a point outside the rotating
fluid?
5. What assumptions are made No viscus force, steady flow, no radial acceleration, valid along a
in deriving the Bernoulli's streamline.

6. What is the physical meaning P or (P/rho(f) *g) is net pressure force, rho(f)*g*z or z is the
of each term in the Bernoul- weight component in the streamline direction, rho(f)*(v^2/z) or
li's equation? (v^2/2*g) is convective acceleration
7. What is irrotational flow/ideal Fluid has no viscosity (u=0)
fluid/non viscous or inviscid
fluid?
8. When can Bernoulli's equa- In general Bernoulli's equation is applicable along a streamline
