Answer:
The answer is below
Explanation:
Given that:
ρ = 800 kg/m3, c = 600 J/kg-K, k = 40 W/m-K, Initial temperature = Ti = 1150,
Environment temperature = T = 450 K, Final temperature = T∞ = 325 K
Diameter = 10 mm = 0.01 m, A = 6
The estimated time for cooling process (t) is given as:
The estimated cooling time is 589 s
Answer:
The dynamic viscosity and kinematic viscosity are 
lb-s/in2 and 
in2/s.
Explanation:
Step1
Given:
Inner diameter is 2.00 in.
Gap between cups is 0.2 in.
Length of the cylinder is 2.5 in.
Rotation of cylinder is 10 rev/min.
Torque is 0.00011 in-lbf.
Density of the fluid is 850 kg/m3 or 0.00095444 slog/in³.
Step2
Calculation:
Tangential force is calculated as follows:
T= Fr
F = 0.00011 lb.
Step3
Tangential velocity is calculated as follows:
V=1.0472 in/s.
Step4
Apply Newton’s law of viscosity for dynamic viscosity as follows:
lb-s/in².
Step5
Kinematic viscosity is calculated as follows:
in2/s.
Thus, the dynamic viscosity and kinematic viscosity are lb-s/in2 and in2/s.
Answer:
Explanation:
During the Second World War, she oversaw the design of production plants for the strategically important materials of penicillin and synthetic rubber.Her development of deep-tank fermentation of penicillium mold enabled large-scale production of penicillin.She worked on the development of high-octane gasoline for aviation fuel.Her later work included improved distillation column design and plants for the production of ethylene glycol and glacial acetic acid.
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.
