Question:
For the same process temperatures, the ratio of the LMTD in parallel flow to the LMTD in counter-current flow in a liquid-liquid heat exchanger is always:
For the same process temperatures, the ratio of the LMTD in parallel flow to the LMTD in counter-current flow in a liquid-liquid heat exchanger is always:
Show Hint
Counter-current flow is more efficient due to higher LMTD values.
