Dear Seniors,
I would like to ask about the pressure change due to temperature change of the test water shall be calculated by using which is formular?
Thank & Best Regards

No. Now, sit down and think through your question again. We cannot answer a poorly phrased question that provides no design background and no parameters.

Yes, in general, water will expand when heated. If the heated water is constrained in a closed container, and that container's volume expands less than the water within it expands, then usually, the internal pressure will go up. But water also contracts when it is heated from 0.0 degree C up to 4 degrees C.

What are you asking, and what is your application to engineering?

An excellent article published in the periodical Chemical Engineering dating back to 2001 and titled "Forestall Pipe Burst contributed by David C. Copenhaver, Lawrenceb A. Coppari and Steve G. Rochelle all from Eastman Chemical Co.. If you can get a copy, it will be a valuable reference. This article deals with thermal expension and is too lengthy to attached as there are 38 equations introduced.
