  • Re: Variation in Weight

    We have addressed importance of cardinal physics priinciples on CR4 before. The same applies here. In any chemical reaction, EXCEPT a nuclear reaction, the weight or mass of the products will always equal that of the materials used at the beginning of the reaction. Certainly, if you weigh ash after...

  • Re: Cold Activated Bottle/Can

    cwarner: It is not the can or bottle that is 'activated' but the labeling. [Chalk this up to the general dumbing down of the American population and the people who feed us this 'content.'] The bottler uses temperature sensitive dyes that activate [turns blue in this case - I think] when the...

  • Re: Fire Tube Boiler Tube leaks

    (the auto pressure regulator doesn't work and the steam pressure and temperature is maintained by opening a manual block valve). Two things jump out at me, pressure and thermal shock. If you have instrumentation on your boiler and trend the data to a chart recorder or SCADA, I would look for t...

  • Re: can single phase power be 440 v?

    Almost all equipment that runs on a three phase supply, require a control cabinet, which is powered by a single phase step-down transformer, you need this to power contactor coils, control devices, PLC, some motion controllers, pilot lamps, push button common lines, flame monitoring systems, timers,...

  • Re: 4-20mA signal to what to record flow?

    If I'm reading your post correctly, normally you would connect it up to a chart recorder. We similarly do this to HTST's (High Temperature Short Time) Pasteurizers. phoenix911...

  • Re: i'm freezing - please help me.

    Call the customer service department or marketing department of your local electric or gas utility and you might be able to "sweet talk" the use of a 24 hour temperature recorder that has a round paper chart and ink pens. All of the utilities have them, if they feel sorry for you, you could use it f...

  • Hot tropical oceans during Pliocene greenhouse warming

    The impact of the greenhouse gas CO2 on the Earth''s temperature is well established by climate models and temperature records over the past 100 years, as well as coupled records of carbon dioxide concentration and temperature throughout Earth history. However, past temperature records have suggested that warming is largely confined to mid-to-high latitudes, especially the poles, whereas tropical temperatures appear to be relatively stable: the tropical thermostat model.

  • Global temperature reaches record high in June following record warmth in May

    According to NOAA scientists, the globally averaged temperature over land and ocean surfaces for June 2014 was the highest for June since record keeping began in 1880. It also marked the 38th consecutive June and 352nd consecutive month with a global temperature above the 20th century average. The last below-average global temperature for June was in 1976 and the last below-average global temperature for any month was February 1985.
