How long would it take to purge a 10-mm section of a 20-cm diameter pipe using a flow rate of 17 Lmin?
To calculate the time it takes to purge a 10-mm section of a 20-cm diameter pipe, first find the volume of the section. The volume can be calculated using the formula for the volume of a cylinder, ( V = \pi r^2 h ), where ( r ) is the radius (0.1 m) and ( h ) is the length (0.01 m). This results in a volume of approximately 0.000314 m³ or 0.314 L. At a flow rate of 17 L/min, it would take about 0.0185 minutes, or approximately 1.11 seconds, to purge the section.

If a tumor in the trachea is removed that was decreasing the trachea's diameter by half the area of the trachea's cross section and the flow of air through it would what?
The removal of the tumor would effectively restore the trachea's diameter and consequently increase the area of its cross section. This would lead to an improvement in the flow of air through the trachea due to reduced obstruction.
What is diameter of a 104 inch circumference?
Approximately 33.1 inches. If you need it more precise: 33.104256125083159 inches.
What is the field of view if the diameter is 80x?
The field of view would be 80 times the diameter.
I am given the bolometric BC equals -1.46 and the visual magnitude V equals 4.33 of a star. how do you calculate the angular diameter?
The bolometric correction allows you to convert between visual and bolometric (total) magnitude - where the bolometric magnitude includes all radiation emitted by the star, not just visible light. It has nothing to do with the angular diameter.
What is cell is approximately 13 the diameter of the field of vision using high power and the diameter of the field of vision for high power is 600 micrometers what is the size of this?
To find the size of the cell, you can divide the diameter of the field of vision by 13. Given that the diameter of the field of vision at high power is 600 micrometers, the calculation would be: 600 micrometers / 13 ≈ 46.15 micrometers. Therefore, the size of the cell is approximately 46.15 micrometers.
How long would it take to purge a 15-ft section of 6-in.-diameter pipe using a flow rate of 35 cfh in tig?
Area equal pi * r^2. Diameter of six equals radius of three. So according to Google, 9 * pi * (15*12) = 5089 cubic inches. Now, again according to Google, 35 (ft^3) = 60 480 in^3 per hour. I'm going to leave you to figure out the answer from here!
How do you get the diameter if the given radius is three?
The diameter is twice the radius - so, using your example, the diameter would be 6.
If a tumor in the trachea is removed that was decreasing the trachea's diameter by half the area of the trachea's cross section and the flow of air through it would what?
The removal of the tumor would effectively restore the trachea's diameter and consequently increase the area of its cross section. This would lead to an improvement in the flow of air through the trachea due to reduced obstruction.
Which shape would a cross section of earth cut from pole to pole reveal?
My $210 Physical Geography class text book does not have the answer. It just says it would be smaller than the diameter of a cross section through the equator.
If the diameter of a human hair is 0.000095m greater than the spider silk which is 10mm what diameter of circle would you need to represent the cross section of a human hair?
0.000095meters = 0.095mm Dia of Hair = 0.095 + 10 = 10.095mm Diameter = 10.095mm
What is the diameter of 64 inches?
The diameter of 64 inches is simply 64 inches. If you are referring to the diameter of a circle with a circumference of 64 inches, you can calculate it using the formula diameter = circumference/π. In that case, the diameter would be approximately 20.37 inches.

What is the circumference of 1.75 diameter?
The circumference of a circle can be calculated using the formula ( C = \pi \times d ), where ( d ) is the diameter. For a diameter of 1.75, the circumference would be ( C = \pi \times 1.75 ), which is approximately 5.49 when using ( \pi \approx 3.14 ). Therefore, the circumference of a circle with a diameter of 1.75 is about 5.49 units.

What is the circumference if the diameter was 4ft?
The circumference of a circle can be calculated using the formula ( C = \pi \times d ), where ( d ) is the diameter. If the diameter is 4 feet, the circumference would be ( C = \pi \times 4 ) feet, which is approximately 12.57 feet when using ( \pi \approx 3.14 ).
Can nitrogen be used to purge gas pipes before welding?
Yes, and No, Nitrogen can be used to purge gas lines prior to welding, but the correct answer depends on several things, mainly, your welding application. A significant amount of resistance welding applications use N2 as a suitable environment for welding. Other applications use N2 as a purge gas, and then purge the N2 with the process gas. That said, if you were going to be using a different inert gas (Argon, Helium, Xenon, etc.) to provide the actual the actual shield for the weld, then you would still need to displace (purge) the N2 from the lines. The last statement leads to the question of; if you are going to have to purge the lines anyway, why do it twice? The answer to this question is pretty basic. Nitrogen is cheap. If you had to purge a lot of lines, or a large volume of space, you would rather use N2 to drive out the Oxygen and lower the dew point (moisture). Using one of the other welding gases would cost about ten times as much to perform the operation.
