First many thanks for this video, you answered many questions I had in mind, still one if you can explain. I found in a random source that the initial value of f=0.0637.Re^-0.21. if you can confirm this information

Thanks, it is a very good video. But how can I can gain h=8m and T= 12 sn? It is standart? It is open for me? And Where is point of affecting Load? Sea level in strcutural member? Colum is like a cantilever?

Hi Nina, great presentation, thank you. Are the equations for instantaneous velocities and accelerations available in a written document?

Hi, is Morrison equation applicable for structures installed on a river bed? Also how do you define the initial parameters?

Hello 😁, Thank you for your interesting and very clear presentation. From a time series of wave heights, I need to calculate horizontal wave velocity and insert it in the Morison equation… for a certain time and depth, with these calculations I get wave velocity at different position along the wavelength… which one should I consider ? Should I do the integral of the horizontal velocity ? Thank you again ! 😁

Excellent 👍

Hello 😀Thank you, very interesting. So is it possible to use Morison equation to calculate the force on offshore wind turbine piles ? The diameter is large though (18 m), but considering a wavelenght (L) of 200 m the ratio D/L is still below the threshold value of 0.2

thank you ❣❣❣

Please can you update the solver section? Excel has changed the layout and I keep getting an error

Why we found at some literature the power density with 64 π instead 32 π ?

How do you get the equation that has be integrated for drag force? If I am using irregular waves instead, will I still have e^2kz dz? And i can't see where the 2kz came from?

can you please name the reference book , thank you, these videos where so helpfull thanks <3

Hello, thank you very much for a very clear explanations. We have some questions about wave forces, what is the best way to reach you?

Hello, thank you very much for a very clear explanations. We have some questions about wave forces, what is the best way to reach you?

shouldn't we consider the vectorial sum of wave + current speeds instead of calculating wave-induced and current induced drag separately?

You are awesome! Just make it easy! Truly appreciate for sharing this tip!

Can you give me a copy of these tables and curves, please?

many thanks for the interesting video i hope if you give us another example for calculating DRAG forces in the case of intermediate wave and shallow wave to clarify how to perform the integration process in each of them and if you can explain the distribution of drag forces along the structural member

Hellp Nina thanks for the video its very helpful. Howeve any i know how does it compute to 62.2kN?Ive got 621.128kN..Do you have the detail breakdown of the number being used in the formula? Thanks!

Thanks fot the video, Ma'm! It is very useful for beginners like me. My question is how to choose the value of “wave length trial”？it should be given randomly or according to experience？how the different “wave length trial” effect calculated wave length？

Very good explanation. COuld U send please the link please for how to use the solver function in Excel?

Great job Mrs. I thank U very much for this good explanation

Why in some formula of wave power they have 64pi in the denominator instead of 32pi ?

It's very helpful, thank you so much. Algeria

Hi , I am in the process of designing the orifice meter line, I have a problem to calculate the pipe line with the iso5167 standard, please help me .

Terimakasih bu, sangat membantu 🙏🙏🙏

How do I get the excel sheet?

Amazing lecturer

Thanks you doing nice work, please keep it continue your video

Looking at the graphs with the loads as a function of time. What x value have you chosen? I plotted it and I get very similar looking graph for the drag force. But I dont get it for the inertia force. Inertia force is mirrored.

Hi, thank you for sharing your knowledge, it helps me a lot. Greetings.

Mam could you please share reference source .

THANK YOU, AMAZING VIDEO, worked example was great.

Very nice video and spreadsheet!

very informative session thanks !

How to calculate wave length trail

This is a good video. I like to revisit this as a reminder.

Sir my teacher asked to plot total head versus position and then discuss it ? Could you tell me what i should discuss about total head and position?

How to calculate the power of water waves flowing into the sea

@learning4carrer. Thank you Madam. It is easy to understand the concepts with examples. But at 7.38, Why the value of D is 0.03 m instead of 0.3 m?

Excellent explanation. Thank you very much.

This is extremely helpful. Thank you very much.

Thank you. Easy to understand with example

Hello Nina, I found this video very instructive, really appreciated it. I've got one question, in the case of shallow water it won't be any integration since the function doesn't depend on z value, everything is constant and remains the same? also, can I have the name of the book or paper related to this topic? thanks!

What should be done, if the water hammer test did not produce oscillation? I already zoom the X and Y axis and only readout was just a dot and the software "timed out" after closing the fast acting valve. THANKS.

How should I treat the integration if the WEC works with the heaving motion (w, and w')? I'll integrate over x for the (horizontal) length of the device and solve the integral with cos^2?

Nice informative videos, well done! I'm looking for a way to estimate ship heave for a stationary vessel (on DP) relative to nearby wave buoy data. Specifically I'd like to estimate whether adding ballast will reduce the ship heave (the vessel has several large empty mud tanks for supplying offshore platforms).
