Ch3 The Bernoulli Equation The most used and the most abused equation in fluid mechanics. 3.1 Newton's Second Law: F =mav • In general, most real flows are 3-D, unsteady (x, y, z, t; r,θ, z, t; etc) • Let consider a 2-D motion of flow along "streamlines", as

Equation of a plane A point r (x, y, z)is on a plane if either (a) r bd= jdj, where d is the normal from the origin to the plane, or (b) x X + y Y + z Z = 1 where X,Y, Z are the intercepts on the axes. Vector product A B = n jAjjBjsin, where is the angle between the vectors and

Fenske's equation: derivation Multicomponent distillation column design The method is applied to the light key (LK) and to the heavy key (HK) components, under column's condition of total reﬂux. The scheme for such a column is here below sketched. Figure 1

2.3.8. Derivation of the Kronig-Penney model The solution to Schrdinger's equation for the Kronig-Penney potential previously shown in Figure 2.3.3 and discussed in section 2.3.2.1 is obtained by assuming that the solution is a Bloch function, namely a traveling

Chapter 2 Lagrange's and Hamilton's Equations In this chapter, we consider two reformulations of Newtonian mechanics, the Lagrangian and the Hamiltonian formalism. The rst is naturally associated with con guration space, extended by time, while the latter is the

General Equation Derivation: Elastic Collision in One Dimension Given two objects, m 1 and m 2, with initial velocities of v 1i and v 2i, respectively, how fast will they be going after they undergo a completely elastic collision? We can derive some expressions for v

Calculus of Variations 1 Functional Derivatives The fundamental equation of the calculus of variations is the Euler-Lagrange equation d dt ∂f ∂x˙ − ∂f ∂x = 0. There are several ways to derive this result, and we will cover three of the most common approaches. Our

The lecture presents the derivation of the Reynolds equation of classical lubrication theory. Consider a liquid flowing through a thin film region separated by two closely spaced moving surfaces. The fluid pressure does not vary across the film thickness and fluid

Henderson—Hasselbalch equation describes the derivation of pH as a measure of acidity using the acid dissociation constant pKa, in biological and chemical systems. The equation is also useful for estimating the pH of a buffer solution and to ascertain the equilibrium pH in acid-base reactions which will be of use to calculate the isoelectric point pI of proteins.

equation results from aforce balance along a streamline. Acceleration in steady flow is due to the change of velocity with position. 34 Derivation of the Bernoulli Equation The forces acting on a fluid particle along a streamline. Steady, incompressible flow
