Question

For which of the following heat exchange scenarios does the flow direction or the heat exchanger configuration/ arrangement does not influence the performance O Water to gas O Oil to water O Wet or saturated steam to water O Oil to gas

Answer 1

answer is c

for wet or saturated steam to water

because for saturated steam if heat transfer takes place , their occcurs a phase change due to which the lmtd of cross and parllel flow will be same

so the flow direction doesn't influence the heat transfer

these are called phase change heat exchangers
