Escherichia coli bacteria are harvested from a fermentation broth using a disc stack centrifuge with 72 discs operated at 7300 rpm. the outer diameter of the discs is 15 cm, the inner diameter is 7.5 cm, and the half-cone angle is 36 degree. the broth viscosity is 1.25 cp, the liquid density is 1025 kg m^-3, and the smallest cell size is 1.1 mu m. the density of e. coli cells is determined by laboratory measurement to be 1.06 g cm^-3. assume that the centrifuge operates ideally. (a) estimate the maximum throughput of broth in litres h^-1 that can be handled by this system while still achieving the desired separation. (b) the measurement of e. coli cell density has a small error of plusminus 2% associated with it. if the particle density is actually 2% lower than the value provided by the laboratory, what effect does this have on the estimated maximum throughput? what conclusions about predicting centrifuge performance can you draw from this result?

no, i was listening to water by schoolboy q while and i saw this question

explenation:

water isn't wet. wetness is a description of our experience of water; what happens to us when we come into contact with water in such a way that it impinges on our state of being. we, or our possessions, 'get wet'. a less impinging sense experience of water is that it is cold or warm, while visual experience tells us that it is green or blue or muddy or fast-flowing. we learn by experience that a sensation of wetness is associated with water: 'there must be a leak/i must have sat in something.'

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
