If same application on a shell and tube heat exchanger, will the De change

Professor, thank you great video please what book do you use?

Excellent video professor please that book do you use?

Great video please that book do you use?

Thank you great video Please that book do you use?

Impressive 👏👏

Thank! Good Film!

What are the pre reqs for this class professor?

PRAISE THE LORD Alleluea Amen 🙏

Which heat transfer coefficient equation i should use if the water flow was in laminer regime??? Please help

What is the value of length of pipe L in this example?

A double-pipe heat exchanger is used to condense steam at a rate of 120 kg/h at 45oC. Cooling water (seawater) enters through the inner tube at a rate of 1.2 kg/s at 15oC. The tube with 25.4-mm O.D. and 22.1-mm I.D. is made mild steel, k = 45 W/(m K). The heat transfer coefficient on the steam side, ho , is 7000 W/(m2 K and on cooling water side hi = 1100 W/(m2 K). Calculate overall heat transfer coefficient under clean and fouled conditions. What does heat transfer drop due to occuring of fouling. Can you help me answer this question??

I have a question regarding a double pipe heat exchanger which I want to poise to you. If you can provide me your email the. I will sent you the problem ?
