Preheating air by steam for use in a dryer. an air stream at 32.2°c is to be used in a dryer and is first preheated in a steam heater, where it is heated to 65.5°c. the air flow is 1000 kg mol/h. the steam enters the heater saturated at 148.9°c, is condensed and cooled, and leaves as a liquid at 137.8°c. calculate the amount of steam used in kg/h.

Did the proton move into a region of higher potential or lower potential? did the proton move into a region of higher potential or lower potential? because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of higher potential to a region of lower potential. because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of lower potential to a region of higher potential. because the proton is a positive charge and it slows down as it travels, it must be moving from a region of higher potential to a region of lower potential. because the proton is a positive charge and it slows down as it travels, it must be moving from a region of lower potential to a region of higher potential. request answerpart bwhat was the potential difference that stopped the proton? express your answer with the appropriate units.î”v î” v = nothingnothingrequest answerpart cwhat was the initial kinetic energy of the proton, in electron volts? express your answer in electron volts. ki k i = nothing ev request answerprovide feedback
