Which one of the following is not a unit of dynamic viscosity?
Which of the following is the dimension of kinematic viscosity?
Which Force is equal to the product of shear stress due to viscosity and surface area of the flow?
The shear stress at a point in a liquid is found to be 0.03 N/m2. The velocity gradient at the point is 0.15 s-1. What will be its viscosity (in Poise)?
Give the dimensions of the following,i) power ii)kinematic viscosity
Which of the following must be followed by the flow of a fluid (real or ideal)? (I) Newton's law of viscosity.(II) Newton's second law of motion. (III) The continuity equation.(IV) Velocity of boundary layer must be zero relative to boundary.(V) Fluid cannot penetrate a boundary.
Two fluids are flowing through two similar pipes of the same diameter. The Reynold's number is same. For the same flow rate if the viscosity of a fluid is reduced to half the value of the first fluid, the pressure drop will
States that as the velocity of a fluid increases, the pressure decreases. This causes planes to fly .
Pressure decreases when the surface area over which a force is applied increases
Bernoulli’s principle states that the pressure in a fluid decreases as its velocity increases.
According to Charles' Law, temperature and volume have what type of relationship?
