Aprocess fluid having a specific heat of 3500 j/kg∙k and flowing at 2 kg/s is to be cooled from 80 °c to 50 °c with chilled water, which is supplied at a temperature of 15 °c and a flow rate of 2.5 kg/s. assuming an overall heat transfer coefficient of 2000 w/m2 ∙k, calculate the required heat transfer areas for the following exchanger configurations:

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =
