It's not likely that any property of fluids correlates
in any way with any Vatican situation.
If a pipe of X cross sectional area is connected so a fluid flows at a specific velocity, and then a pipe of 2X cross sectional area is connected to the pipe of X cross sectional area, the velocity of fluid flowing in the 2X pipe will be less than what is flowing in the X pipe. In this case, what you're saying is true.

How does resistivity vary if length and area are doubled?
if length is doubled then resistivity increases&when area is doubled resistivity decreases.
Volume and surface area of prisms a?
Volume = cross sectional area * lengthArea = 2* cross sectional area + perimeter of cross section * length
What happens to the cross-sectional area of metal wire if you double the diameter?
If the diameter doubles (x2), the cross-sectional area quadruples (x4).
How does the cross sectional area of wire affect resistance?
Other things being equal, more cross-sectional area will cause less resistance.
What is the relationship between velocity and cross sectional-area?
According to Kepler's second law of planetary motion, the line joining a planet to the sun covers equal areas in equal time intervals.
What is the relationship between cross sectional area of blood vessel and velocity of blood flow in that vessel?
Proceeding downstream from the aorta, branching of arterial vessels increases total cross-sectional area and thus results in diminished velocity of blood flow from the aorta to the capillaries. Velocity increases from the capillaries to the large veins with the confluence of vessels and the resulting decrease in total cross-sectional area. :)
How come Bernoullis principle say that as pressure decreases velocity increases when we know that as area increases pressure decreases we also know that as area decreases velocity increase?
By area do you mean cross sectional area of a stream tube? Bernoulli's principle only compares pressure and velocity and it covers all fluids. In the case of an ideal gas (constant density) decreasing the cross sectional area of a stream tube lets say; will not affect the pressure. But given any fluid volume..going from point a to point b if velocity decreases, particles in the fluid want to move outward. just remember any fluid must do two things move and apply pressure.
Does resistance increase as the cross-sectional area of the wire?
the resistance can never increase or decrease....... (you can't open the resistor and take out the something and make the resistance increase or decrease)AnswerSince resistance is directly proportional to the length of a conductor, increasing the length of a wire will increase its resistance. For example, if you double its length, you will double its resistance.
Seepage velocity and discharge velocity?
Discharge Velocity is obtained by Dividing the Total Discharge by the total cross Sectional Area , Where Total cross sectional area Consists of void+solid. In contrast .. Seepage Velocity is defined as the total discharge by the Area of voids only. So Seepage velocity always greater than Discharge Velocity.
The velocity of blood flow is?
slowest in the capillaries because the total cross-sectional area is the greatest
Why aren't large particles of matter carried as high in the wind as the smaller ones are?
It has to the with the ratio of cross-sectional area to volume. If an object expands in size while keeping the same proportions the ratio of its cross sectional area to its volume decreases. If we assume a constant density, then the ratio of cross sectional area to mass increases as well. For example, if we take a sphere and double its diameter, its volume will increase eight times while its cross-sectional area will only increase four times. The force an object experiences from wind is proportional to its cross-sectional area while the maximum force holding it in place is usually proportional to its mass.
What type of wire increases when it is made thinner?
Since resistance is inversely-proportional to cross sectional area, the lower the cross-sectional area, the higher the resistance. So ALL types of wire exhibit this behaviour!
Why can't the wind lift and carry large particles?
It has to the with the ratio of cross-sectional area to volume. If an object expands in size while keeping the same proportions the ratio of its cross sectional area to its volume decreases. If we assume a constant density, then the ratio of cross sectional area to mass increases as well. For example, if we take a sphere and double its diameter, its volume will increase eight times while its cross-sectional area will only increase four times. The force an object experiences from wind is proportional to its cross-sectional area while the maximum force holding it in place is usually proportional to its mass.

What is discharge in geography?
Discharge is the volume of water passing a given point over a set of time. To calculate discharge you do: Mean velocity x cross sectional area Steeper slopes should lead to higher velocities because of the influence of gravity. Discharge normally increases downstream, as does width, depth and velocity.
How do you do a cross sectional area of a rectangle?
You cannot create a cross sectional area of a rectangle. You can only create cross sectional areas for triangular shapes.
How does resistivity vary if length and area are doubled?
if length is doubled then resistivity increases&when area is doubled resistivity decreases.
