 Lecture 1 Play Video The Basic Equation of Pressure Field In this video lesson, Physics Instructor Donny Lee will analyze the forces on a water particle, and derive the basic equation of the pressure field, a highly important equation when dealing with change in pressure. Lecture 2 Play Video Pressure Field Incompressible Fluid In this video lesson, Physics Instructor Donny Lee will use the basic equation, and find the pressure field of an incompressible fluid assuming density constant. Lecture 3 Play Video Forces at a Point for Basic Equation In this video lesson, Physics Instructor Donny Lee will analyze the surface forces on a water particle on a fluid to later derive the basic equation. Lecture 4 Play Video Pressure at a Point (Part 1) In this video lesson, Physics Instructor Donny Lee teaches that the pressure at a point in a fluid is the same regardless of the direction the pressure is directed to. Lecture 5 Play Video Shearing Stress On Disk In this video lesson, Physics Instructor Donny Lee analyzes the shearing stress of a rotating disk. Lecture 6 Play Video Pressure at a Point (Part 2) In this video lesson, Physics Instructor Donny Lee teaches about the pressure at a point in a fluid, which is the same regardless of the direction the pressure is directed to. Lecture 7 Play Video Viscosity In this video lesson, Physics Instructor Donny Lee teaches about Viscosity. Lecture 8 Play Video Pressure Variation With Motion In this video lesson, Physics Instructor Donny Lee studies the pressure variation in a fluid with rigid-body motion. The key assumption, among others, is that there is no shearing stress between water particles. Lecture 9 Play Video A Cup of Coke in a Moving Vehicle In this video lesson, Physics Instructor Donny Lee will analyze the pressure variation in a cup of coke when it is in a vehicle that is accelerating. Lecture 10 Play Video Hydrostatic Force In this video lesson, Physics Instructor Donny Lee teaches about hydrostatic force. Lecture 11 Play Video Centroid and Centre of Pressure Not Equal In this video lesson, Physics Instructor Donny Lee will derive the location of a hydrostatic force on a plane surface. It turns out that the center of pressure and centroid are not the same. Lecture 12 Play Video Archimedes' Principle: The Mathematical Way In this video lesson, Physics Instructor Donny Lee brings a mathematical approach to derive Archimedes' principle. We find the magnitude of the Buoyancy force here. Lecture 13 Play Video Archimedes' Principle: Location of Force In this video lesson, Physics Instructor Donny Lee brings a mathematical approach to derive Archimedes' principle. We find the location of the buoyancy force here. Lecture 14 Play Video Hydrostatic Force On Plane In this video lesson, Physics Instructor Donny Lee will derive the magnitude and direction of a hydrostatic force on a plane surface. Lecture 15 Play Video Pressure Field Compressible Fluid In this video lesson, Physics Instructor Donny Lee uses the basic equation, to find the pressure field of an compressible fluid assuming density constant. Lecture 16 Play Video Hover Craft via Reynold's Theorem In this video lesson, Physics Instructor Donny Lee does an analysis of the hover craft with Reynold's Transport Theorem. We find the velocity function. Lecture 17 Play Video Transport Theorem Complex Case In this video lesson, Physics Instructor Donny Lee looks further into Reynold's Transport Theorem by considering the system of particles and control volume as an arbituary shape. Lecture 18 Play Video Analysis of Forces in One Dimension In this video lesson, Physics Instructor Donny Lee looks at the forces acting on a water particle flowing through a tube in one dimension leading up to Reynold's Transport Theorem. Lecture 19 Play Video System vs Control Volume In this video lesson, Physics Instructor Donny Lee elaborates on the difference between a system analysis and a control volume analysis. Lecture 20 Play Video Reynold's Transport Theorem in One Dimension In this video lesson, Physics Instructor Donny Lee will derive Reynold's Transport Theorem in One Dimension. Lecture 21 Play Video Hovercraft (Part 2) In this video lesson, Physics Instructor Donny Lee will calculate the force required to suspend the craft above the water. Lecture 22 Play Video Syphoning Water In this video lesson, Physics Instructor Donny Lee will use Bernoulli's equation to explain a common phenomena in syphoning water. Lecture 23 Play Video Flow Past a Sphere In this video lesson, Physics Instructor Donny Lee studies a flow of a fluid with a complex velocity function and see how Bernoulli's equation gives us the velocity and pressure relationship. Lecture 24 Play Video Bernoulli's Equation (After Integration) In this video lesson, Physics Instructor Donny Lee gets Bernoulli's Equation by carefully considering each term. Lecture 25 Play Video Bernoulli's Equation via F = ma In this video lesson, Physics Instructor Donny Lee will start a tour into Bernoulli's Equation by resolving forces.
