b) 0.0337

c) 2730.206 Ib

d) 2320.338 ft/min

Explanation:

<u>a) Plot of the drag polar for this aircraft </u>

first we will calculate :

Wing area (s) = Wing span (b) * Average chord length(c)

= 53.3 * 6 = 319.8 ft^2

Aspect ratio = b^2 / s = 8.883

K = 1 / $\pi$ eAR = 1 /

Drag polar ( Cd ) = 0.02 + 0.044 C^2L

attached below is a plot of the drag polar

Two vertical parallel plates are spaced 0.01 ft apart. If the pressure decreases at a rate of 60 psf/ft in the vertical z-direct

Whitepunk [10]

Answer:

umax = 0.1259ft/s

Explanation:

Given:

•Distance between plates, B = 0.01ft

•Pressure difference decrease, $\frac{dp}{dz}=60ps/ft$

•Fluid viscosity, u = 10^-³lbf-s/ft²

Specific gravity, S = 0.80

Max velocity in the z-direction will be:

$u_max= [\frac{B^2y}{8u}]\frac{dh}{ds}$

$But h = \frac{P}{y}+z$

Substituting for h in the first equation, we have:

$\frac{d}{dz}[\frac{p}{y}+z]$

$\frac{dh}{dz}=\frac{1}{y}\frac{dp}{ds}+\frac{dz}{dz}$

$= \frac{1}{0.8*62.4}(-60)+1$

= -0.20192

Substituting dh/dz value in the first equation (umax), we have:

$umax = \frac{0.01^2(0.8*62.4)}{8*10^-^3}(-0.20192)$

umax = 0.1259ft/s

Solve the problem with conditions if a wall has inner and outer surface temperatures of 16 and 6 C, respectively. The interior a

Angelina_Jolie [31]

Answer:

Heat flux is 20 W/m^2

Explanation:

Heat flux (Q) is computed as

$Q = h \, \Delta T$

where h is heat transfer coefficient and ΔT is the difference between body's temperature

From the interior air to the inner wall

$Q = 5 \frac{W}{m^2 K} \, 4 K$

$Q = 20 \frac{W}{m^2}$

From the the outer wall to the exterior air

$Q = 20 \frac{W}{m^2 K} \, 1 K$

$Q = 20 \frac{W}{m^2}$

The wall is under steady-state condition because heat flux is constant
