 Title: Celebrating India's Engineering Excellence: September 15 - Engineering Day Introduction:- On September 15th, India celebrates Engineering Day, a day dedicated to honoring the remarkable contributions of engineers to the nation's development and progress. This special day commemorates the birthday of one of India's greatest engineering visionaries, Sir Mokshagundam Visvesvaraya. As we delve into the significance of Engineering Day in India, let's explore the life and achievements of this iconic figure and the broader importance of engineering in the country. Remembering Sir M. Visvesvaraya Sir Mokshagundam Visvesvaraya, born on September 15, 1861 , in Muddenahalli, Karnataka, was a renowned Indian engineer, statesman, and scholar. He is celebrated for his pioneering contributions to engineering, particularly in the field of irrigation and flood control. His most notable achievement is the design and construction of the KRS Dam (Krishna Raja Sagara Dam) in Mysore

 Fluids can be classified into different categories based on various properties and characteristics. Here are some common ways to classify fluids: 1. Based on Physical State:  • Liquids: These are fluids with a definite volume but no fixed shape. Examples include water, oil, and milk.  •Gases: Gases have neither a definite shape nor a fixed volume. They expand to fill the container they are in. Examples include oxygen, nitrogen, and carbon dioxide. 2. Based on Behavior Under Pressure:    • Compressible Fluids:  Gases are highly compressible, meaning their volume can change significantly under pressure. They are easily compressed into smaller volumes.    • Incompressible Fluids: Liquids are relatively incompressible. Their volume changes very little under pressure, making them suitable for hydraulic systems. 3. Based on Viscosity:    •Viscous Fluids:  These are fluids with high viscosity, meaning they flow slowly and offer significant resistance to motion. Examples include honey and mol
