Derive an expression for critical velocity
WebBecause velocity is a vector and a vector has not just a magnitude which would be its speed but also its direction, so even if I have the same speed at this point as I have at … WebDOSAG derivation.doc --- Page 5 To protect fish, engineers often want to know the minimum oxygen concentration that can be expected as a result of a waste discharge. This is called the critical point (critical from the point of view of the fish). The travel time to the lowest point in the sag is the critical time. Using the critical time (t

Viscous damping is damping that is proportional to the velocity of the system. That is, the faster the mass is moving, the more damping force is resisting that motion. Fluids like air or water generate viscous drag forces. Figure : A diagram showing the basic mechanism in a viscous damper.
WebApr 7, 2024 · The derivation of terminal velocity using Mathematical terms according to the drag equation comprehensive stepwise equations to arrive at the desired equation. First we use the formula for the free fall of the object then we derive the equation assuming that free fall happens in the positive direction. WebIf vB be the critical velocity of the particle at the bottom, then from conservation of energy. Mg (2R) + 1/2 mvT2 = 0 + 1/2 mvB2. As vT = √gR => 2mgR + 1/2 mgR = 1/2 mvB2. Thus, Note: In case the particle is …
