In a shell and tube heat exchanger, which fluid flows through the tubes?

The fluid that needs to be stored

The fluid that needs to be filtered

What is the formula for calculating Log Mean Temperature Difference (LMTD)?

LMTD = (ΔT1 + ΔT2) / (ln(ΔT1 / ΔT2))

LMTD = (ΔT1 * ΔT2) / (ln(ΔT1 / ΔT2))

LMTD = (ΔT1 - ΔT2) * (ln(ΔT1 / ΔT2))

LMTD = (ΔT1 - ΔT2) / (ln(ΔT1 / ΔT2))
