Gas Consumption Estimate

The lower graph looks more-or-less like the integral of the upper, which makes sense. However, the upper graph is surprisingly step-wise. Do none of the loads modulate?

Should read Daily.

But daily of what?

Household? Gas turbine? The latter should have a flat line and consume gas constantly.

Your variable usage looks a lot like hot water system with storage container with a more or less unsuffcient isolation (unless you see the bathroom in the night frequently).

Wake up time in the household 6 am and 6 pm it goes towards bedtime. Not sure what you do from 9-10.

Whats you say?

No, this does not look at all like the laughing gas consumption rate I would expect from any dental practice.

Could this possibly be bovine flatulence gas production for a dairy farm?

The upper graph looks like the Seattle skyline lead in to Frasier.

The second graph does not look like a curve.

Also, you do not identify what is consuming the gas.

Those who saw your first post understand it is a hypothetical household (we assume) consumption graph.

Maybe you should have put it in the other thread?

Unreadable.

I see this as household, and I see 1st step as furnace, 2nd step as hot water heater (maybe), and the little spike as the stove. Why is there a boiler and a furnace? I don't get it. And a gas dryer. OK, great. Yes, each household appliance will represent a "constant" burn rate for the time it is on, and there are at least five appliances, not including any backyard ceramic oven, or grill. Are you having a peeing contest with your local gas company?

Or are you planning to make your gas and use it? I don't think you will have enough.

The font and image is so small on my screen that I'll assume your clarification. With the exception of the spike for the stove and the flurry of spikes for the oven at noon, I wonder about the length of time for all of the rest of the gas burners. I would expect more brief burns than shown. If a timed rollback household thermostat was used, then I would expect these longer burns when the indoor temperature level setting had just raised and longer dead periods when the level had just dropped. A furnace that had to run for three of the first four hours between midnight and 3:00 AM is close to being overwhelmed by heat demand. It seems odd then that from 3:00 AM to 4:00 AM (the coldest part of most nights) for the furnace to never run.

That's assuming his 24 hours is midnight - midnight. It might not be.

The pitiful amount of clear information in this thread mandates that assumptions must be made. This is one of the threads that I wonder if the OP is more interested in seeing what attributes we assume in an attempt to answer a question than the answer we provide.

Redfred.. I think you and lyn (whom I suspect is Lyndon Larouche based on the way he talks) are the only two people left on on this site left who really contribute it seems.. What are you doing to bolster participation on this once flourishing fourm except to show off you knowledge with sarcasm on us who are less fortunate to not have the age and wisdom to know as much as you know.. In short, it will help you if you are more graceful in you critisism

Sir, I am insulted by your postulation that Lyn and Redfred are the only responders. First of all, I doubt you even read any of the other responses, and secondly, why even post at all, if all you want to do is argue about it? Take it for what it is, and move on.

If I seem upset, it is because I opened my water and electric bill last night and saw where I was being charged >$1600 for water last month (February for those in Rio Linda), corresponding to consumption of 236,000 gallons. It appears (1) the water meter was not even cleaned off when I inspected it, so there's no way they read the meter, and (2) the CSP wanted to argue with me, assuming I was just one more of the brain dead masses out there griping about my bill. If I had used that much water, the place would be under water about 2 ft, by my quick estimate, although the runoff would have been tremendous. There is no leak, and the meter was not even turning when I inspected it. I say it's an outrage, and an insidious fraud!

Who has a gas meter calibrated to read in L/min? Did they actually go to the trouble to install some other meter than what the gas company uses?

They did that to my landlord recently. she was charged 1000$ for water for the 1 month, checked the meter, it was not even moving, no leaks..

by the way..

l liter per minute x 0.035 cubic foot per liter x 60 minutes per hour = 2.12 cubic foot per hour

typical furnace cycling rates are this long based on what I have seen from actual measurements ppl have made, there are a lot of variables, but I want to get it as realistic as possible

I make that average ~ 16 kW (input power) over the 24 hours. Not unreasonable for a house in winter. From the consumption rates there are clearly several appliances.

Yes, it looks very reasonable provided the following:

Between 3:00 and 4:00 AM your house self heats.

Your alarm comes on at 5:00, you make coffee at 5:15, they are both gas powered, highly inefficient, and the coffee costs you about $4.00 per cup.

You have a pool party between 9:00 and 11:00, then go to work until 12:00.

You get home at 12:15 and reheat your house using the oven.

You nap between 1:00 and 2:00, then take a shower, which empties the water heater.

Around 4:00 you begin pulsing all appliances in the house, and finish cleaning the dishes at 7:45.

Gas powered TV time starts at 8:45, and lasts 20 minutes.

You go to bed at 9:20 and get back up for another shower at 10:50 (you go stud).

Am I close?

Well..The rates are in liters/min.. maybe that why u think the values high

I'm just spinning your wheel a little.

It's actually a pretty good chart analysis.

Well, I suppose I assumed a colder setting.. the furnace loads were based on actual data i found from a Minnesota home in winter.. the furnace cycles every hour or so, with longer periods towards the coldest part of the day (3-5am).. the rest, i came up with assuming multiple occupancy, like laundary and cleaning during the day etc..

Hi,

I am not an expert and new in this field but I want to say that the second gas consumption graph is more understandable.

...............................

gas and gasoline

So whats the story?

Input has been given.

Something more from your side? What is it all about?

Yeah, 10% input and 90% ridicule...

You get what you pay for!

Besides I think your scratched ego might have the numbers wrong as all I see is 90% input and 10% ridicule. Not bad for a non de-script question.

While the question seems ok for what it was, it'd be still interesting to know why you would make up a graph like this and why you would ask that question?

Is your objectivity spoiled by your own work not to be able to tell yourself that it could well be a gas usage graph from what ever you want it to be?

I am curious so please fill me in.

why you would make up a graph like this and why you would ask that question?

well, I have been looking for some information like this to do some analysis on energy usage but it is difficult to find it. So i figured i'd make it up to be as realistic as possible. My assumptions are based on occupant habits and app. characteristcs..

also, i have asked ppl i know, but all found it uncomfortable with me messing with their meters, and understandably so

i would be spared all this if i owned my own home and i would just measure it, but in this economy, who can afford such a luxury..
anyway, i just wanted to see if other can see it without much explanation, bc. if i have to explain it in detail, it would not be the same as looking at the graph and getting ur first impression..
thanks for your input by the way..

You should have stated this was "hypothetical" in the first place. Toward what end are you doing this? You want to make a "smart" system for consumers to show them what they already know?-- that their gas bill is high in winter? Is this so you can calculate savings based on geothermal system? What?

You want to make a "smart" system for consumers to show them what they already know?
NO! You know that smart meters are used for spying on people.
