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

Q2. What is centre of gravity? write the formula to calculate it for an assymetrical I section
Ans. 
Centre of gravity is the point where the entire weight of an object can be considered to act upon. Formula for an asymmetrical I section is (A1*d1 + A2*d2)/(A1+A2)
• Centre of gravity is important in designing structures and machines to ensure stability and balance

• It is the point where the object will balance perfectly in any orientation

• For an asymmetrical I section, the formula is (A1*d1 + A2*d2)/(A1+A2) where A1 and A2 ...read more
