OT: Name of fluid/gas flow diagram

I'm reviewing some process documentation that includes a number of fluid/gas flow diagrams. Components shown are pumps, valves, heat exchangers and other stuff.

Each flow has a four parameter label, laid out in a cross shape. The upper left value is mass flow (kg/S), the upper right is heat (enthalpy?) (kJ/kg), the lower left is pressure (bar), and the lower right is temperature (°C).

Does this diagram have a particular name? One which I might Google in order to educate myself and not appear a complete idiot in preliminary design meetings with mechanical engineers (I know, too late ;-)).

It would be easier if you could post a sample somewhere, but it sounds like a PFD - Process Flow Diagram, AKA a flagsheet. PFDs show the main flow paths, and include stream information such as you describe. The more common Process & Instrument Diagram (P&ID) incluides every line and vessel, and everything hanging off them. Working out what a process does from a PFD is much easier than with a P&ID, generally with the latter you need someone with process knowledge to walk you through it, and a highlighter pen to mark the important bits.

My rule of thumb: if you can't find it on Wikipedia, it's too esoteric for anyone to expect you to know what it is.

I tried Googling some of your terms. Nothing came up with the sort of labeling I'm seeing. Its possible that this is something of this ME's own invention. But it makes too much sense to be something that others don't use. With the labeling legend, its pretty easy to figure out. But I want to round out my knowledge of the associated jargon.

Due to this engineer's misspelling of water vapor as "watre vapour", I'm guessing that he (she) is not from the USA. But then I'm seeing that a lot on most engineering projects these days. So this might be a common type of diagram someplace like India or China.

And _my_ rule of thumb is that it's better to look ignorant and honest than to look like a poseur.

In other words -- if you don't know, you can only make things better by asking.

when I encountered it 20 years ago in a UI design class I think it was called a "face graph" but "glyph plot" seems to be the current term.

Every designer outfit has their own convention for details like surrounds, boxes, placement etc. Having the stream data inside some sort of shape doesn't characterise the diagram in any way AFAIAA. With so many international sources of engineering projects these days it's no surprise that variations in presentation are becoming more common. Very likely to be a PFD or something similar.

It's a PFD, fairly standard layout. Nothing special.
