Q3. What is meant by LNTD
Ans. 
LNTD stands for Logarithmic Mean Temperature Difference.
• LNTD is a term used in heat transfer calculations to determine the overall temperature difference between two fluids in a heat exchanger.

• It is calculated using the formula LNTD = (ΔT1 - ΔT2) / ln(ΔT1 / ΔT2), where ΔT1 and ΔT2 are the temperature differences at the two ends of the heat exchanger.

• LNTD is important in designing efficient heat exchangers to maximize h...read more
