Answer:
The answer is as given in the explanation.
Explanation:
The 1st thing to notice is the assumptions required. Thus as the diameter of the cylinder and the wind tunnel are given such that the difference is of the orders of the magnitude thus the assumptions as given below are validated.
- Flow is entirely laminar, there's no boundary layer release.
- Flow is streamlined, ie, it follows the geometrical path imposed by the curvature.
By D'alembert's paradox, "The net pressure drag exerted on a circular cylinder that moves in an inviscid fluid of large extent is identically zero".Just in the surface of the cylinder, the velocity profile can be given in the next equation:
And the pressure P on the surface of cylinder is given by Bernoulli's equation along the streamline through that point:
where P_∞ is Pressure at stagnation point, U is the velocity given, ρ is the density of the fluid (in this case air) and θ is the angle measured from the center of cylinder to the adjacent point where your pressure point will be determine.

Answer:
A turbo blade has the best features from both other types of blade. The continuous, serrated edge makes for fast cutting while remaining smooth and clean. They are mostly used to cut a variety of materials, such as tile, stone, marble, granite, masonry, and many other building materials.
Explanation:
Machining is a process in which a metal is cut into a desired final shape and size by a controlled material-removal process. Machining is a part of the manufacture of many metal products, but it can also be used on materials such as wood, plastic, ceramic, and composites.
Answer:
The average loss for this device is $10.90
Explanation:
Given data
Specification = 24 +/- 0.4 Amps
average quality cost = $32.00
average value y = 23.9
standard deviation s = 0.211 Amps
32 = k(24.4 - 24)²
32 = k(0.4)² = k(0.16)
k = 32/0.16 = 200
To evaluate average loss, use
L = k{s² + (y - T)²}
T = 24A
L = 200{0.211² + (23.9 - 24)²}
L = $10.90
The average loss for this device is $10.90
