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.
As the cross-sectional area of a conductor Increases the conductor..?
As the cross-sectional area of a conductor increases, its resistance decreases. This is because a larger area allows more electrons to flow through the conductor, reducing congestion and increasing conductivity. Consequently, the larger cross-sectional area decreases the resistance to the flow of current.
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.
What is the relationship between flow velocity and area?
Flow velocity and area are inversely related in a fluid system. When the area decreases, the flow velocity increases, and vice versa, according to the principle of continuity, which states that the product of cross-sectional area and flow velocity remains constant in an enclosed system with steady flow.
Is the resistance of the wire directly or inversely proportional to the cross-sectional area of the wire?
The resistance of a wire is inversely proportional to the cross-sectional area of the wire. This means that as the cross-sectional area of the wire increases, the resistance decreases, and vice versa.
How does resistance change when the cross-sectional area of a wire changes?
When the cross-sectional area of a wire increases, the resistance decreases because there is more space for current to flow through, reducing the likelihood of collisions between electrons and the wire material. Conversely, if the cross-sectional area decreases, the resistance increases because the available space for the current to flow through is reduced, leading to more collisions and hindering the flow of electrons.
Does resistance increase as the cross-sectional area of the wire?
No, resistance decreases as the cross-sectional area of the wire increases. This is because a larger cross-sectional area provides more pathways for the electrons to flow through the wire, resulting in less resistance.
What are the factors affecting the resista nce of a wire?
The factors affecting the resistance of a wire are its length, cross-sectional area, resistivity of the material, and temperature. As the length of the wire increases, the resistance also increases. A larger cross-sectional area decreases resistance, while higher resistivity materials and increased temperature contribute to higher resistance.
What effect will the cross-sectional area of the conductor have on the resistance of a conductor?
The cross-sectional area of a conductor is inversely proportional to the resistance of the conductor. Increasing the cross-sectional area decreases the resistance, as it allows more space for electrons to flow through, reducing collisions and increasing conductivity. Alternatively, decreasing the cross-sectional area increases resistance, as there is less area for electrons to flow through, leading to more collisions and increased resistance.
When area reduces velocity increases or decreases?
When the area reduces, the velocity typically increases due to the conservation of mass principle, which states that the product of the cross-sectional area and velocity of a fluid remains constant, assuming steady flow. This relationship is described by the continuity equation. However, changes in area alone may not be the only factor affecting velocity, as other variables such as pressure gradients or frictional losses can also influence the flow velocity.
How do you calculate velocity of water in channel?
You can calculate the velocity of water in a channel using the formula v = Q/A, where v is the velocity, Q is the flow rate of water, and A is the cross-sectional area of the channel through which the water is flowing. By knowing the flow rate and the cross-sectional area of the channel, you can determine the velocity of water.
How does the 4 factors affect the resistance?
The four factors that affect resistance are material, length, cross-sectional area, and temperature. Resistance increases with longer length and higher temperature, and decreases with greater cross-sectional area and more conductive material. These factors impact the ability of a material to impede the flow of electrical current.
