Estimate the weight of 25 km of gas pipeline, DN = 610 mm and wall thickness = 12.7 mm.
1 answer:
Answer:
Weight = 45880 kN
Explanation:
Gas pipeline material is steel.
Density of steel = 7850 kg/m³
Mass = Volume x Density
Volume = Area x Length
Outer diameter = 610 mm
Internal diameter = 610 - 2 x 12.7 = 584.6 mm
Length = 25 km = 25000 m
Volume = 25000 x 0.0238 = 595.78 m³
Mass = 595.78 x 7850 = 4676875.12 kg
Weight = Mass x Acceleration due to gravity = 4676875.12 x 9.81 = 45880 kN
Weight = 45880 kN

Answer:
Applied voltage should be 13.5396 kV
Explanation:
The charge stored by a capacitor when subjected to a potential difference 'v' across it's plates is given by
Solving for V we get
thus to store a charge of 0.11mC we solve for V as follows
Applying values we get
The color of a star would with that surface temperature would be White. Hope this helps. :)
'D' is one way to increase the current. Another way is to increase the voltage. / / / It's possible that 'C' might also be a true statement. We don't know; because we can't see it.
