For an ideal fluid, the bulk modulus is?

What is the dynamic viscosity of water at 30°C?

A liquid weighs 1000 kg and has a volume of 2 m³. Calculate the specific gravity of the liquid.

The body will float if the force of buoyancy is equal to the weight of the liquid displaced.

A tank has a height of 70 m and a base area of 10 m². If the tank is filled at a velocity of 2 m/s, what is the rate of flow (discharge)?

A fluid flowing through a pipe of diameter 450 mm with velocity 3 m/s is divided into two pipes of diameters 300 mm and 200 mm. The velocity of flow in the 300 mm diameter pipe is 2.5 m/s. What will be the velocity of flow through the 200 mm diameter pipe?

Here are three cases of equilibrium:

1. Stable equilibrium

2. Unstable equilibrium

3. Neutral equilibrium

What happens to the potential energy in these three cases?

Choose the correct option accordingly.

The flow through a circular pipe is initially laminar. Now, the fluid through the pipe is replaced with a more viscous fluid and passed through the pipe again with the same velocity. What can we say about the nature of this new flow?

For steady flow of a viscous incompressible fluid through a circular pipe of constant diameter, the average velocity in the fully developed region is constant. Which one of the following statements about the average velocity in the developing region is TRUE?

The knowledge of External Flow dynamics is critical because it finds many applications in various industries. Boundary layer formation and eddy formation are very complex to analyze analytically. Hence, we use numerical techniques to solve the problem. Although numerical methods are semi-automatic and can be done just by entering a few values, there are certain things we should take care of. Which of the following is correct for external flow dynamics?
