The temperature difference between the hot and cold fluids in a heat exchanger is given to be T 1 at one end and T 2 at the other end Can the logarithmic temperature difference T lm of this heat exchanger be greater than both T 1 and T 2 Explain

Question: The temperature difference between the hot and cold fluids in a heat exchanger is given to be T 1 at one end and T 2

The temperature difference between the hot and cold fluids in a heat exchanger is given to be ΔT₁ at one end and ΔT₂ at the other end. Can the logarithmic temperature difference ΔT_lm of this heat exchanger be greater than both ΔT₁ and ΔT₂? Explain.
