Nothing flammable of explosive type of material is around
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. True
Explanation:
MATLAB may be defined as a programming platform that is designed specifically for the engineers as well as the scientists to carry out different analysis and researches.
MATLAB makes use of a desktop environment which is tuned for certain iterative analysis and the design processes with a programming language which expresses matrix as well as array mathematics directly.
Thus the answer is true.
Answer:
The correct option is: 2. Propane
Explanation:
Minimum ignition energy, abbreviated as MIE, is the minimum energy required to ignite the flammable mixture of air at atmospheric pressure and room temperature. The unit used to measure this energy is millijoule, mJ
The values of the minimum ignition energy for the following gases are:
Butane = 0.25 mJ
Propane = 0.26 mJ
Ethylene = 0.07 mJ
Hydrogen = 0.017 mJ
Cyclohexane = 0.22 mJ
<u>Therefore,among the following gases, Propane requires the most ignition energy, 0.26 mJ. </u>
