Water Hammer Analysis

Are you looking for a water hammer calculator? If so, check out this site.

Wangsa,

Can you be more explicit?

I don't know what you mean by GD2, or the relevance to water hammer in calculating the dimension of a flywheel.

The question makes no sense to me.

Regards, Greg

I am posting a copy of Wangsa's E-mail to me in the hope that someone more knowledgeable than I in this area can assist him in some better way:

"GD² is moment inertia.I must calculate dimension of fly wheel for mycrohydro, based on GD² pump (pump have moment inertia and fly wheel too). for calculate GD² pump is based on water hammer analysis ( in picture is not turbin but pump). In this project the pump is changed as turbin. would you help me? may be you could tell me about water hammer equation for calculate GD² for pump.

Since the drawing you sent only very approximately relates to your question, a lot more information on your part would be required for me to assist you, to the extent I was able.

Hopefully someone here who has been involved in similar design efforts can refer you to some helpful sites.

Regards, Greg

I really don't know what the question means, but I can think of a couple of things that may apply.

1. An expansion chamber on the pump side can help even the transmission of energy to the shaft. 2. A hydraulic pump?

Waiting with great anticipation to see this one unravel...
