...de façon à assurer une émission résultante la plus proche d'une loi linéaire. ...in a manner that assures the resulting output is as close to linear as possible. Explanation: "Output," is here, speaking of flow through the gate. |

...de façon à assurer une émission résultante la plus proche d'une loi linéaire. so the ensuing outflow is as close at possible Explanation: to a linear flow path law... as in Darcy's law Linear flow paths assumed in Darcy’s law -------------------------------------------------- Note added at 13 mins (2005-02-17 23:19:10 GMT) -------------------------------------------------- correction: so the ensuing outflow is as close as possible to a linear flowpath This is apparently Darcy\'s law -------------------------------------------------- Note added at 13 mins (2005-02-17 23:19:44 GMT) -------------------------------------------------- Have a nice holiday by the way -------------------------------------------------- Note added at 14 mins (2005-02-17 23:20:34 GMT) -------------------------------------------------- in hydraulics, the term is flowpaths...:) -------------------------------------------------- Note added at 15 mins (2005-02-17 23:21:09 GMT) -------------------------------------------------- and an emission in hydraulics is outflow...as opposed to inflow.. |

...in such a way as to ensure that the resulting output follows a linear law as far as possible Explanation: Just an alternative take, very close to the original, of course, but a couple of point may be important. 1) I'm not entirely convinced that this 'emmision' is referring in fact to the flow of water (etc.) --- that might well be 'débit', as used in the previous phrase. I think we could be talking about, for example, heat output [once again, Asker, a little bit more background context could save a lot of head scratching here!] --- this is to some extent born out by the fact that the 'quantity' being measured for control purposes is temperature. 2) And I think tha 'linear law' being referred to is not some specific law of physics, but rather, the 'control law' [a term often used in technical contetxts] --- it basically means that if you set the control to ¼, you get ¼ of the desired result, if you set it to ½, you get ½, and so on... I think they are taking a very overall view here, and saying that the COMPLETE control loop of setting thermostat / temperature sensor / control circuit / motorized valve / heat output device (e.g.) must give an OVERALL linear law, when all these factors are combined. Of course it can never be perfect, but sophisticated, modern, computerized systems can do a pretty good job. Reduced to its simplest level, it would mean that when the valve lever (etc.) is in mid-position, the flow should be 50%, etc. All does depend on the wider context, but these are the sort of points I would be looking to consider... -------------------------------------------------- Note added at 8 hrs 48 mins (2005-02-18 07:54:30 GMT) -------------------------------------------------- Oh, dear, sorry about those typos: points émission the :-( -------------------------------------------------- Note added at 15 hrs 58 mins (2005-02-18 15:04:59 GMT) Post-grading -------------------------------------------------- In reply to Jane\'s rather tart response, I was moved to investigate dear Monsieur Darcy and his fascinating law, only to discover that it relates to the flow of fluids through granular or permeable materials, and is specifically relevant in disciplines like hydrology --- so quite frankly, I think it is way off context here for a heating valve; but maybe Jane will be able to show me just how wrong I am... ;-) |
