It quadruples.
The circumference of a circle divided by its diameter is equal to the value of pi
It will result to the circle's radius.
The circumference is also quadrupled.
If the diameter doubles (x2), the cross-sectional area quadruples (x4).
you have a severe pressure drop and a loss of velocity
As the gas flows from a larger diameter pipe to a smaller one, its speed increases due to the conservation of mass principle. The pressure of the gas decreases as per the Bernoulli's principle. The spacing between the streamlines decreases since the velocity increases in the smaller diameter pipe.
Blood pressure increases if the diameter of the blood vessel decreases.
it could get cloged if u put to much in at the same time u have to put it in little by little
Pressure rises at the junction.
Due to friction between the fluid and the walls of the pipe, pressure increases within the pipe.
Due to friction between the fluid and the walls of the pipe, pressure increases within the pipe.
Assuming that the pressure remains at a constant, reducing the diameter of the pipe will increase the water flow. On the contrary, increasing the diameter would cause the water to flow at a much slower rate.
The diameter of a circle is doubled if the circumference is doubled.
If the diameter of the rod is increased but the oil flow remains the same, the retraction speed of the cylinder rod will decrease. This is because a larger diameter rod requires more volume of oil to fill, resulting in slower movement when the same amount of oil is flowing through.
Then the current will stop flowing.
You get 2 circles of diameter. If you were trying to find a perimeter, Never double the diameter. If you have a radius, You have to double it to get a perimeter.
