Are you sure ?, from where have you brought this !? Could you proof that? If that is true so what does that mean? How could multiplication results in the second derivative !? regards

From above definition this just a dot product so just need to multiply ∂∂x i by ∂∂x i isn't that we do when we take dot product of two vectors;multiplication !?

Shouldn't the answer be first derivative squared !? \left(\frac{\partial}{\partial x}\right)^{2}

Hi guys The Laplace Operator The Laplace operator is defined as the dot product (inner product) of two gradient vector operators: When applied to f(x,y), this operator produces a scalar function: My question is how a vector dot product ( del operator vector dot product...

!??

Any help!?

Determine Flow rate for pipeline ! Hi all I want to design two piping system for IVF (In vitro fertilisation) Lab. That first pipeline carries CO2 and the other one carries Nitrogen/Oxygen Mixture. The problem that encounters me is to determine the flow rates form the equipment for the...

I totally agree

I have not worked with Ansys before but I assure you that Solidworks simulation is rather easy to use and "user-friendly" and has way high capabilities.

I guess confusion came from that on some papers they use gauge pressure on sometime and absolute pressure on other times, they say: The pressure after regulator is 2 PSI (gauge pressure), however when they want to talk about the atmospheric pressure they say it is 14.7 PSI Thank you xxChrisxx...

I have not claimed that I have written this by myself, I have just wanted to ask question and I wanted to make things clear so as to understand me well and if this will add a new info for others -Knowing how their gas burner works- I will be pleased.

Hi guys I have a question regarding the working principle of gas burner. I was always have this question " How gas burner works using gas pressure lower -after been regulated- than atmospheric air ? " Won't the the atmospheric air pressure prevent the gas from flowing? [SIZE="4"]Gas Burners...

Hi Thank you all for contribution. Here are more info : http://fluorotherm.com/Properties-PCTFE.asp" http://fluorotherm.com/Properties-PTFE.asp" http://www.wisegeek.com/what-are-elastomers.htm" http://www.pspglobal.com/sab.html" http://www.pspglobal.com/viton-properties.html"

Thank you very much edgeflow for you continuous assistance, these info are very helpful What about PCTFE? I have to pipelines, One for CO2 and the other is special mix gas (89% nitrogen , 6% CO2 , 5% Oxygen) for (IVF lab) and I use stainless steel for whole installation and PCTFE, but there...

Hi all I want you to give a comparison between PTFE / PCTFE / Viton / EPDM O-ring considering these points : • nonflammability • excellent chemical resistance to all inorganic corrosive fluids • Thermal resistance • friction • practically zero moisture absorption • excellent...
