sample problem in rotating vessel

1. sample problem in rotating vessel

When at rest, the surface of mass of liquid is horizontal at PQ as shown in the figure. When this mass of liquid is rotated about a vertical axis at constant angular velocity ω radian per second, it will assume the surface ABC which is parabolic. Every particle is subjected to centripetal force or centrifugal force CF = mω2x which produces centripetal acceleration towards the center of rotation. Other forces that acts are gravity force W = mg and normal force N.  

2. Open cylindrical vessel 0.60 m in diameter contains water of 0.90 m deep when at rest. if it is rotated about its vertical axis at a speed of 180 rpm, determine the least depth the vessel can have so that no water is spilled over the

3. Question 20/60 A 90-degree conical vessel of height 2m carries of water whose volume is one half of the of the cone. Find the speed in rpm at which the vessel may be rotated to make the water just spill out. 17.27 18.10 18.68 19.54

Answer:

A 90-degree conical vessel of height 2m carries of water whose volume is one half of the of the cone. The speed in RPM at which the vessel may be rotated to make the water just spill out is approximately 18.68 RPM.

4. please helppp 1. 90° clockwise rotation 2. 270° clockwise rotation 3. 90° counterclockwise rotation 4. 180° counterclockwise rotation

1.A 90° clockwise rotation is equivalent to flipping an image or object 90° to the right. For example, if you rotate the letter "L" 90° clockwise, it becomes the letter "J".

2.A 270° clockwise rotation is equivalent to flipping an image or object 90° to the left or 90° clockwise three times. For example, if you rotate the letter "L" 270° clockwise, it becomes the letter "T".

3.A 90° counterclockwise rotation is equivalent to flipping an image or object 90° to the left. For example, if you rotate the letter "L" 90° counterclockwise, it becomes the letter "7".

4.A 180° counterclockwise rotation is equivalent to flipping an image or object 180° or upside down. For example, if you rotate the letter "L" 180° counterclockwise, it becomes the letter "└".

5. A SHIP IS ABOUT TO SINK DUE TO AN ICEBERG WHEN THREE RESCUE VESSELS COME. EACH VESSEL WAS CARRYING 50 PASSENGERS WHEN THE RESCUER NOTICED THAT IS NOT SAFE FOR ALL THE PASSENGERS SINCE THE VESSELS WERE NOT OF THE SAME SIZE. AS KNOWN BY THE RESCUER, THE PASSENGERS ON BOARD IN EACH VESSEL SHOULD BE IN THE RATIO 2:3:5. HOW MANY PASSENGERS SHOULD BE TRANSFERRED FROM VESSEL A TO VESSEL B TO VESSEL C FOR THE SAFETY OF ALL PASSENGERS?

6. what vessels that supplies unoxygenated blood from small vessels?

Answer:

7. Why should every opening on a vessel must be secured? (vessel is a ship)

Answer:

If the storage of cargo is not secure enough then there is no escape from the behavior of the seas and the wind once they show their rage. This in result takes a toll on the loaded cargo, causing damage to other cargo in the vicinity or to the vessel's structures and fittings and even throwing the cargo overboard.

10. if a rotation is performed on a coordinate plane, what angles of rotation would make the rotation easier?

Predicting Rotations

Rotate the point (5, 8) about the origin 270° clockwise. The rule for rotating an object 270° clockwise about the origin is to take the opposite value of the x coordinate and then switch it with the y coordinate. The opposite of 5 is -5 and, switching the coordinates, we obtain our answer: (8, -5).

Answer:

11. In which kind of blood vessel does oxygen move through the vessel wall?

ARTERIES ARE BLOOD VESSELS WHERE OXYGEN MOVE THROUGH THE VESSEL WALL.
If you mean the blood vessel carrying oxygenated blood it will be the arteries, but if mean the blood vessel where oxygen can diffuse through its wall it be the capillaries because its wall is only one cell thick, so thin that it allows gaseous material to pass through it.

12. 7. In a closed vessel, one gram of substance A is placed where 50% of it was converted to substance B and C. How would you describe the nature of substance in a vessel now? * O The vessel is a mixture composed of substance A, B, and C O The vessel is a compound composed of substance A, B, and C O The vessel is a pure substance O The vessel is composed of elements

19. Why can lymphatic vessels transport larger molecules than blood vessels?

[tex]\large{}[/tex]

Why can lymphatic vessels transport larger molecules than blood vessels?Lymphatic capillaries have extra permeability than blood capillaries and therefore can take in massive molecules consisting of proteins and lipids. Lymphatic capillaries also are barely large in diameter than blood capillaries and feature a completely unique one‐manner shape that lets in interstitial fluid to circulate them however now no longer out.

Explanation:

The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.

The Earth's rotation happens because its axis runs from the North Pole to the South Pole. It takes the Earth 24 hours, or one day, to make one complete rotation around this invisible line. As the Earth rotates, each area of its surface gets a turn to face and be warmed by the sun.
