Question 2
a) A laminar boundary layer profile may be assumed to be approximately of the form
u/Ue= f (n)=f(y/8)
i) Use an integral analysis with the following two-segment velocity profile,
ƒ (n)=(n/6)(10–3n−1³), for 0≤7≤0.293 and ƒ (7) = sin (л7/2) for 0.293≤n≤1,
to find expressions for the displacement thickness &*, the momentum thickness e,
the shape factor H, the skin-friction coefficient c, and the drag coefficient CD.
ii) Derive an expression for the velocity normal to the stream wise direction given that,
u/U₂ = f(n).
iii) Hence obtain the velocity normal to the stream wise direction for the above two-
segment velocity profile.
A free particle moving along positive x-axis encounter three regions as shown in the figure.
The wave functions of the particle in region 1 and region 2 are of the form 4(x) = Asin(kx-
wt). Where k=2T/A is a wave number and wt = o is the phase term. In region 1, the
amplitude of the wave function A1=11.5, wavelength A1 = 4.97 nm and phase = -65.3°.
The wavelength in region 2 is A2 = 10.5 nm. The boundary C is located at x = 0, and the
boundary D is located at x = L, where L = 20 nm. Using the mathematical features of wave
function, find the amplitude of the wave function and the phase in region 2. (A2 and ø2)

If the spring constant is k = 2.2 N/m, can you find the mass of the cart? If you can do it, give the answer here. If you can't, put 0.m = _______ kg The simple mass on a spring is the basis for our description of almost any oscillation. Lets consider the vibrational states of a simple diatomic molecule, say N2. We will model it as two identical masses connected by a spring as shown in the figure at the top right.This is a little different from the cart on a spring since there is no wall -- both of the atoms are moving. But if we only look at oscillations of the molecule where the center of mass is not moving, the atoms are moving equally and oppositely. When one is going left, the other goes an equal amount to the right and vice versa. This is like two carts attached to a wall and oscillating equally and oppositely as shown in the lower picture. The only difference is the way we treat the spring. When each atom moves a distance x, the spring between the atoms actually stretches…arrow_forward

Long wavelength waves, traveling deep in the ocean, have a speed given approximately by v 2π Where g is the acceleration due to gravity. Short wavelength waves, corresponding to surface ripples, have a velocity given approximately by 2πT λρ Where p is the density of the water and T is the surface tension. Show that the group velocity for long wavelength waves is times their phase velocity and the group velocity for short wavelength waves is times their phase velocity. v=arrow_forwardHomogeneous Linear Differential Equations with Constant Coefficients✓ VIBRATIONS OF SPRINGarrow_forwardP13.28 Normalize the set of functions $„(0) = eino, 0 ≤ 0 ≤ 2π.
