What does curvature ratio mean in tubing?
Radius of curvature divided by tube diameter. To get the radius of curvature, imaging the bend in the tube is a segment of a circle, the radius of curvature is the radius of that circle.
A cardboard tube has diameter 4 inches About how many inches of tape are needed to wrap around the mouth of the tube 3 times?
The answer is 38.
What force is needed to bend 1.5 inch square in tubing?
it depends on both the tube wall thickness and the length of the bend and how much you bend it. Otherwise you cannot determine force.
How do we express the the sum of a tube and four?
tube + 4.
How many cubic yards of concrete to fill a 4 foot tube?
We need to know the dimensions of the tube. The diameter AND the length of the tube. It takes o.465 yards per foot of length for a tube 4 feet in diameter. .
How do mosquitoes get to your blood?
Mosquitoes feed on blood by sucking from the hosts body by means of a fine tube called the proboscus. This syringe like tube is very sharp, it is inserted into the skin at the selected site. An anti-coagulant is squirted into the area to prevent clotting of the blood until the mosquito has fed. It is an intolerance, or allergy, to this anti-coagulant that causes the annoying itch later.
What tube do you use for coagulant testing?
Light Blue. The additive in these tubes is usually Na+ Citrate and there is a marking on the test tube to indicate the minimum fill. Blood must come at least up to the line or it will not be acceptable.
Collection tube containing an anti-coagulant inverted how many times?
Typically, a blood collection tube containing an anticoagulant should be inverted 5-8 times gently to ensure thorough mixing of the blood with the anticoagulant, which helps prevent clotting. Over-inverting may cause hemolysis and affect test results.
What color tube that requires a 1.9 ratio of anticoagulant to blood?
A light blue tube typically requires a 1.9 ratio of anticoagulant to blood. This tube is often used for coagulation studies.
What color is the tube that blood is drawn in for an anti DNA test?
The tube for an anti-DNA test is typically purple on the top and lavender on the bottom, known as a lavender-top tube. This tube contains EDTA, an anticoagulant that helps preserve the blood sample for testing.
What is the ratio ofanticoagulant and blood in the black tube?
The typical ratio of anticoagulant to blood in a black tube is 1:9, meaning there is 1 part anticoagulant to 9 parts blood. This ratio helps prevent the blood from clotting and allows for accurate testing of blood samples.
What is the ratio for luo color mixed with releaser?
For Luocolor with releaser the ratio is 1/1.5, so if you are using a tube of luo (50ml) you would mix it with 75ml of releaser. The instructions are inside the tube of luocolour aswell.
How do you know what color blood collection tubes to use?
The color of the blood collection tube is designed to match the additive inside it for specific tests. Healthcare providers follow guidelines on which color tube to use based on the type of test being performed, ensuring accurate and reliable results. It's important to always consult the laboratory manual or guidelines provided for proper tube selection.

if it is scanned by an anti-virus
What amount of force is needed to bend tube mital?
It depends on the thickness of the tube, the diameter of the tube and the shear strength of the material.
Why is the charge to mass ratio of proton not constant?
The charge and mass ratio of proton is constant, the positive particles found during discharge tube experiment are nuclei of atoms which have different charge and mass ratio.
What is the correct color tube for thrombin test?
The correct color tube for a thrombin test is typically a light blue tube. This tube contains sodium citrate as an anticoagulant, which is needed for coagulation studies.
