Saturated process steam (1 atm, t 100'c, he 2,257 kj/kg) is condensed in a one-shell one-tube pass heat exchanger. a liquid stream (p 998 kg/m', cp = 4,181 j/kg-k, μ = 959 x 10" ns/m, k 0.606 w/m-k) enters the thin-walled copper tubes of 14 mm diameter and 3 m length at 15°c with an average velocity of 2 m/s. if the convective heat transfer coefficient for condensation outside the tubes is 21,800 w/m'k, determine: a) (20 points) the number of tubes n required to condense 5 kg of steam per second. b) (5 points) the outlet temperature, ts of the liquid stream. c) (5 points) the condensation rate, that can be achieved with this heat exchanger using the same liquid stream flowrate and inlet temperature.

b. acid is the correct answer @jayxboof all social media

acid : acids are those which accepts an electron-pairs.

base : bases are those which donates ab electron-pairs.

alkali : it is a base that dissolves in water. it is basically a base and the ph greater than 7.

hydroxide ion : it is a poly-atomic ion which is negatively charged.

did anyone actually do this? like if anyone has submitted this i rly need .

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.
