The cylindrical portion of short length, which connects converging and diverging section of venturimeter, is called as
diffuser
connector
throat
manometer tube
Which of the following devices does not use Bernoulli's equation as its working principle?
Venturimeter
Orifice-meter
Pitot tube
None of the above
What is the correct formula for Euler's equation of motion?
Where,
ρ = density of the fluid
p = pressure force
g = acceleration due to gravity
v = velocity of the fluid
(∂p / ρ) + (∂g / ρ) + (∂v / ρ) = 0
(∂p / ρ) + (∂g / ρ) + (v dv) = 0
(∂p / ρ) + (g dz) + (v dv) = 0
(p dp) + (g dz) + (v dv) = 0
What is an ideal fluid?
A fluid which has no viscosity
A fluid which is incompressible
A fluid which has no surface tension
All of the above
Newton's law of viscosity states that
the shear stress applied to the fluid is directly proportional to the velocity gradient (du/dy)
the shear stress applied to the fluid is inversely proportional to the velocity gradient (du/dy)
the shear stress applied to the fluid is directly proportional to the specific weight of the fluid
the shear stress applied to the fluid is inversely proportional to the specific weight of the fluid
