What is the effect of reducing the radius of the air flow tube on respiratory volumes?
Volumes can be the same if you lengthen the time of inhalation or exhalation but your flows will be reduced significantly. The effect of radius on air flow is a relationship that is to the power of 4. As an example, if you decrease the radius by half, the flow rate is reduced to 1/16th of the original (1/2 squared and then squared again).
This is why a slight reduction in radius can be quite severe. For asthmatics and those with COPD, the problem often isn't getting air in as much as getting air out.

What is the effect of reducing afferent arteriole radius on filtration?
reducing afferent arteriole radius decreases filtration rate
What is a height of a cylinder if the radius is 3 and the volumes 250?
h = 8.84
How can you find the ratio of radius of two cones when you have the ratio of volumes of that two cones?
You cannot because the volumes of the cones also depend on their heights.
What is the effect of reducing afferent arteriole radius on filtration rate?
As the afferent arteriole dilates it exposes the glomerulus to an increased blood pressure, closer and closer to that of the full systemic blood pressure. This increases GFR and Glomerular pressure. -6th Year Medical Student
How do you decrease he size of a circle?
By reducing its radius or diameter.
How does the wheel radius affect the effort needed to turn the wheel?
A larger wheel radius typically requires less effort to turn the wheel because the larger radius provides a mechanical advantage, allowing the force to be applied further from the center of the wheel. This results in a greater leverage effect, reducing the amount of force needed to turn the wheel. Conversely, a smaller wheel radius would require more effort to turn the wheel due to the decreased leverage effect.
How many times greater is the volume of a sphere with a radius of 5 than a radius of 2.5?
Volumes: 523.5987756/65.44984695 = 8 times greater 53/2.53 = 8
Describe the effect on the area of a circle when the radius is doubled?
the radius is from the center of the circle to the edge so that's how you find the radius.
What effects the cylinder more doubling the radius or doubling the height?
They both have the same effect on the surface area of the pipe, but the radius has more effect on its volume/capacity.
How many spheres of mercury each with a radius of r should combine to form a single sphere with a radius of 3r?
Volume of the sphere varies as the cube of the radius.Tripling the radius increases the volume by a factor of (3)3 = 27.It takes 27 spherical volumes with radius 'r' to fill one spherical volume with radius '3r'.
How did changing the radius effect FEV1?
Decreased the FEV1 %
How much does the volume of a sphere increase if the radius doubles?
Since the volumes depends on the radius to the 3rd power, we can look at 2r and note that it is 8x larger. For example if we start with radius 2 and make it 4, we note that 23 =8 and 43 =64 which is 8x8.
