Mean temperature difference in an exchanger. a 1-2 exchanger with one shell pass and two tube passes is used to heat a cold fluid from 37.8 c to 121.1 c by using a hot fluid entering at 315.6°c and leaving at 148.9℃ calculate the δτǐn and the mean temperature difference δ7, in k. δ7," = 148.9 k.37,-131.8 k

1. calculate the approximate enthalpy of the reaction in joules. estimate that 1.0 ml of vinegar has the same thermal mass as 1.0 ml of water. iqnore the thermal mass of th sodium bicarbonate. note: it takes about 4.2 joules () to change 1.0 gram (1.0ml) of water 1.0 c
