Answer:
The rate of cell metabolism is limited by mass transfer since the value of maximum cell concentration obtained (38 g/l) is lower than 50 g l-1, the value planed.
Explanation:
Data
<u>kLa</u> = 0.17/s
<u>Solubility of oxygen</u> = 8 × 10^-3 kg / m^3
<u>The maximum specific oxygen uptake rate </u>= 4 mmol O2 / g h.
<u>Concentration of oxygen</u> = 0.5 × 10^-3 kg/ m^3
<u>**The maximum cell density</u> = 50 g/l
___________________
The calculated maximum cell concentration:
xmax= kLa · CAL*/ qo
CAL* is the solubility of oxygen in the broth and qo is the specific oxygen uptake rate
Replacing the data given
xmax= ( 0.17/s ) · (8 × 10^-3 kg / m^3) / 4 mmol O2 / g h
4 mmol O2 / g h to kg O2/ g s
= 3.56 x 10^-3 kg O2/ g s
So then,
xmax= ( 0.17/s ) · (8 × 10^-3 kg / m^3) / 3.56 x 10^-3 o kg O2/ g s
xmax= 3. 8 x 10^4 g/ m^3 = 38 g/l

Answer:
Heat flux is 20 W/m^2
Explanation:
Heat flux (Q) is computed as
where h is heat transfer coefficient and ΔT is the difference between body's temperature
From the interior air to the inner wall
From the the outer wall to the exterior air
The wall is under steady-state condition because heat flux is constant

Explanation:
Cutting tools:
1. Cutting tools can either be single point or multi point.
2. Cutting tools can have variety of material depending on use like ceramics, diamonds, metals, CBN, etc.
3.Cutting tools have definite shapes and geometry.
Abrasive machining tools
1. Abrasive tools are always multi point tools.
2. Abrasive tools composed of abrasives bounded in medium of resin or metal.
3. They do not have definite geometry of shape
Answer:
The thing that separates the work of technology transfer research from implementation of the products of such research is:
Technology transfer research looks at how technology may be transferred but does not actually make the transfer.
Explanation:
This suggests that technology transfer research is different from the technology transfer (implementation) itself. The first stops at making scientific investigations into technology transfer activities while the next step performs the actual transfer or implementation. In other words, technology transfer conveys the results of scientific and technological research to the marketplace and to the wider society. It is the bridge-builder between the research and the implementation.
Answer:
Blue
Explanation:
You want me to overthink it which is why I think the answer should be the most obvious and not the most complicated
