The order should be:
3, 5, 1, 4, 2, 6
Answer:
0.0432 m^3/s
Explanation:
Internal diameter of smaller pipes = 2.5 cm = 0.025 m
pipa wall thickness = 3 mm = 0.003 m
internal diameter of larger pipes = 8 cm = 0.8 m
velocity of region between smaller and larger pipe = 10 m/s
Calculate discharge in m^3/s
First we calculate the area of the smaller pipe
A =
=
= 0.00023571 m^2
next we calculate area of fluid between the smaller pipes and larger pipe
A = ![[\frac{\pi }{4} D^{2} _{L} ] - 3(A_{s})](https://tex.z-dn.net/?f=%5B%5Cfrac%7B%5Cpi%20%7D%7B4%7D%20D%5E%7B2%7D%20_%7BL%7D%20%20%5D%20-%203%28A_%7Bs%7D%29)
= ![[ \frac{\pi }{4} (0.08 )^2 - 3 ( 0.00023571 )]](https://tex.z-dn.net/?f=%5B%20%5Cfrac%7B%5Cpi%20%7D%7B4%7D%20%280.08%20%29%5E2%20-%203%20%28%200.00023571%20%29%5D)
= [ 0.00502857 - 0.00070713 ]
= 0.00432144 m^2
hence the discharge in m^3/s
Q = AV
= 0.00432144 * 10
= 0.0432 m^3/s
Sleeve scale Micrometer features are given below.
Explanation:
Measurements taken with micrometer are a combination of the value shown on the sleeve scale and the value indicated on the rotating sleeve scale.
- The value of the first significant figure of a measurement can be found on the sleeve scale.
- This will be the number immediately to the left of the thimble.
-
On a metric micrometer, this will be given in millimetres. Each minor increment on the sleeve scale represents 0.5mm.
-
In this example, the reading on the sleeve scale is 6.5mm.
- Each number on the sleeve of the micrometer represents 5 millimeters (mm) or 0.005 meter (m).
- Each of the 10 equal spaces between each number, with index lines alternating above and below the horizontal line, represents 0.5mm or five-tenths of a mm.. One revolution of the thimble changes the reading one space on the sleeve scale or 0.5 mm.
- The beveled edge of the thimble is divided into 50 equal divisions with every fifth line numbered: 0, 5, 10,5. Since one complete revolution of the thimble advances the spindle 0.5mm, each graduation on the thimble is equal to one hundredth of a millimeter.
- As with the inch-graduated micrometer, the three separate readings are added together to obtain the total reading.
