Imma take a guess and say it’s a project portfolio but I wouldn’t put that bc I don’t see an image
Answer:
Some of the demerits or disadvantages of using a very slow castings rates in production of metal by the method of casting includes, with the solidification of metal, it may begin even before the mold is filled fully, which may result in defects such as shrinkage.
Secondly, the rate of slow casting will create castings that have a grain coarse structure that will affect the strength of the castings.
Explanation:
Solution
The disadvantageous of slow casting rates in the production of metals by casting method is explained below:
(1) The solidification of metal may start even before the mold is filled completely, which may create or produce defects such as mis-runs and shrinkage and shrinkage cavity.
So, the slow cavity rate will produce partial and incomplete castings
(2) Slow casting rate will produce castings which have a coarse grain structure which therefore affects the strength of the castings adversely.
Answer:
It's one of the key standards of science, and it's critical to the point that it has become data a significant number of us underestimate. Realizing that every single living thing are comprised of cells permits us to see how creatures are made, develop, and kick the bucket. That data encourages us see how new life is made, why living beings take the structure they do, how malignant growth spreads, how maladies can be overseen, and that's only the tip of the iceberg. Cells even assist us with understanding principal issues, for example, life and passing: a creature whose cells are living is viewed as alive, while one whose cells are dead is viewed as dead. Illness, how creatures develop, and passing were substantially more of a puzzle contrasted with what we know today.
Explanation:
The cell theory is one of the primary hypotheses of science. It has three primary parts:
- Every single living thing are comprised of cells.
- Cells are the fundamental structure squares of life.
- All cells originate from previous cells made through the procedure of cell division.
As our logical information has expanded after some time, extra parts have been added to the theory. Schleiden and Schwann, just as Virchow, are for the most part observed as the organizers of the cell theory, because of their spearheading logical work during the 1800s. The cell theory is significant in light of the fact that it influences about each part of science, from our comprehension of life and passing, to how we oversee ailments, and the sky is the limit from there.
Different pieces of the cell theory since they weren't a piece of the first definition, yet it's as yet valuable to know about them:
- Vitality stream happens inside cells.
- Innate data is passed from cell to cell.
- All cells have a similar fundamental substance piece.
A high voltage!! Hope this helps
Based on the calculations, the absolute pressure in the pipe is equal to 90,670.4 N/m².
<h3>How to calculate the absolute pressure?</h3>
Mathematically, absolute pressure can be calculated by using this formula:
<u>Scientific data:</u>
Atmospheric pressure (Patm) = 1 bar = 1 × 10⁵ N/m²
Head (h) = -70mmhg = -0.07 m hg
Acceleration due to gravity = 9.8 m/s²
Density of mercury = 13,600 kg/m³.
Next, we would determine the gauge pressure:
Now, we can calculate the absolute pressure:
Absolute pressure = 90,670.4 N/m².
