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.

c is the answer because when something is left after something evaporates that shows the chemical change.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.

i believe the answer is three water molecules
