An experiment on the growth rate of certain organisms requires an environment of humid air enriched in oxygen. Three input streams are fed into an evaporation chamber to produce an output stream with the desired composition.
A: Output gas totals 74 moles
B: Air (21 mole% O, the balance N)
C: Pure oxygen, with a molar flow rate one-fifth of the molar flow rate of stream B
The output gas is analyzed and is found to contain 3.0 mole% water. Draw and label a flowchart of the process, and calculate the volumetric and molar flow rate of water into the system, the molar flow rate of air into the system, and the mole fractions for the output stream.
1. What is the Volumetric Flow rate of water into the system (cm3/min)?
2. What is the molar flow rate for Water (mole/min)?
3. What is the molar flow rate of pure O2 into the system (mole/min)?
4. What is the mole fraction of O2 in the product stream (moles of O2/total moles)?

An experiment on the growth rate of certain organisms requires
an environment of humid air enriched in oxygen. Three input streams
are fed into an evaporation chamber to produce an output stream
with the desired composition. A: Liquid water, fed at a rate of 80
cm3/min B: Air (21 mole% O2, the balance N2) C: Pure oxygen, with a
molar flow rate 0.49 times the molar flow rate of stream B The
output gas is analyzed and is found to...

Researchers are interested in the effect of a certain nutrient
on the growth rate of plant seedlings. Using a hyproponics growth
procedure that used water containing the nutrient, they planted six
tomato plants and recorded the heights of each plant 14 days after
gemination. Those heights, measured in millimeters, were as follows
: 55.5, 60.3, 60.6, 62.1, 65.5, 69.2. Test the claim that the mean
tomato plants’heights is different than 65 millimeters. Assume the
random sample assumption holds. Use α...

WRITE COMPLETE SOLUTION.
4. The growth rate of a certain colony of bacteria in
a controlled room temperature is given by the expression
dP(t)/dt = -4.375x10^-5 P(t)^2 + 0.0525P(t)
Where:
P(t) = bacterial count
t = time
Initial biomass count was performed by the researchers
and found a total of 400 grams.
Determine:
a) The time when population reaches 500 grams.
b) The time when population reaches 850 grams.
c) The time when half of the maximum growth rate is...
