Asugar solution (p-1080 kg/m3, cp 3 601 j/(kg. k), ky 0.576 4 w/(m-k), and u 1.3 x 10 n-s/m-) flows at a rate of 60 000 kg/hr and is to be heated from 25°c to 40°c. water at 95 c is available at a flow rate of 75 000 kg/hr. it is proposed to use a 12-in.-id, 1-2 shell and tube heat exchanger containing 3/4- in.-od, 16 bwg tubes, 1 m long and laid out on a 1-in. square pitch. the exchanger contains three baffles spaced evenly. will the exchanger be suitable? if not, can it be made to work by doubling the flow rate of the water? find outlet temperatures for the configuration that works when the exchanger is new

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance
