Welcome to Prime Career Coaching Academy Sheringal! In this detailed and SEO-optimized lecture for Class 11 Physics (KPK Textbook Board, Chapter 6: Fluid Dynamics), we dive into the essential concept of Speed of Efflux using Torricelli's Theorem. Presented by Sir Irshad, this video is perfect for 1st Year FSc/Intermediate students preparing for KPK Board exams. Learn how to calculate the speed at which fluid exits a container, with derivations, examples, and exam tips!
What is Speed of Efflux and Torricelli's Theorem?
Torricelli's Theorem states that the speed of efflux (v) of a fluid from a small hole in a container is equal to the speed of a body falling freely from the same height (h) as the hole from the fluid surface: v = √(2gh), where g is acceleration due to gravity (9.8 m/s²). This theorem, derived from Bernoulli's equation, explains fluid discharge in tanks and is a core topic in Fluid Dynamics (Chapter 6).
Key Concepts Covered in This Video:
Introduction to Speed of Efflux: The velocity at which fluid jets out from an orifice under pressure.
Derivation of Torricelli's Theorem: Step-by-step proof using conservation of energy and Bernoulli's principle (P + ρgh + ½ρv² = constant).
Assumptions: Ideal fluid (incompressible, non-viscous), small hole, and steady flow.
Factors Affecting Speed: Height (h) above the hole, fluid density (ρ), and gravity (g)—no direct dependence on container size.
Real-Life Examples:
Water leaking from a tank or garden hose.
Firefighting nozzles and fuel tank discharge.
Applications in hydraulic systems and irrigation.
Numerical Problems: Solved examples calculating efflux speed, range of jet (R = 2h √(2h/g)), and time of flight, aligned with KPK Board syllabus.
Relation to Bernoulli's Equation: How Torricelli's is a special case (negligible pressure difference at hole).
Exam Tips: Strategies to solve Torricelli's theorem questions in MCQs and long problems for KPK Board exams, including coefficient of velocity corrections.
This video is optimized for students searching for speed of efflux class 11, Torricelli's theorem kpk board, or fluid dynamics chapter 6 explained. With clear animations, board-aligned examples, and practical insights, we make this topic straightforward and exam-ready. Ideal for KPK Textbook Board students!
