1️⃣ What is density?
✅ Density is a fundamental property of matter that describes how much mass is contained in a given volume of a substance.
✅ It helps us understand how “heavy” or “light” a material is for its size.

💡Simple Explanation:
✅ If you take two cubes of the same size — one made of iron and the other made of wood — the iron cube feels heavier because it has more mass packed into the same volume, meaning it has a higher density.
2️⃣ What is viscosity?
✅ Viscosity is the property of a fluid that describes how thick or sticky it is — in other words, it measures a fluid’s resistance to flow.

💡Simple Explanation:
✅ If you pour water and honey at the same time, you’ll notice that water flows quickly while honey flows slowly.
✅ That’s because honey has a higher viscosity — it resists motion more than water does.
3️⃣ Bearnouli's equation:
✅ Bernoulli’s Equation is one of the most important principles in Fluid Mechanics.
✅ It describes how energy is conserved in a moving fluid — showing the relationship between pressure, velocity, and height at different points in a fluid flow.

💡Simple Explanation:
As a fluid moves, it has three forms of energy:
a). Pressure Energy (P/ρg) – Energy due to the fluid’s pressure
b). Kinetic Energy (V²/2g) – Energy due to the fluid’s motion
c). Potential Energy (z) – Energy due to its height above a reference point
4️⃣ Continuity equation:
✅ The continuity equation is one of the most fundamental principles in fluid mechanics.
✅ It expresses the law of conservation of mass, meaning fluid cannot be created or destroyed as it flows through a system.

💡 Simple Explanation:
✅ Imagine water flowing through a pipe.
✅ If the pipe becomes narrower, the velocity of the fluid increases to ensure the same amount of water passes through every second.
✅ So — when area decreases, velocity increases, and vice versa.
5️⃣ Pressure and Head:
✅ Pressure is the force exerted by a fluid per unit area on the walls of its container or any surface it touches.
✅ Head represents the height of a fluid column that produces a specific pressure.
🔄 Relationship Between Pressure and Head:
✅ Pressure = Force per area (useful for calculations)
✅ Head = Height (easy to visualize)
