Hi Stan,
Article looks OK . one though did cross my mind - is it worth stating that power is to energy as speed is to distance - speed being distance flow? Regards _____ From: [email protected] [mailto:[email protected]] On Behalf Of Stanislav Jakuba Sent: 09 September 2011 16:33 To: U.S. Metric Association Cc: Don HIllger; aaj Subject: [USMA:51105] Calculations easy Note: This e-mail was apparently "blocked" as some of the earlier ones were. Here is a new attempt. Some of you may have noticed the "Metrication at Otis Elevator Company" article in the latest issue of METRIC TODAY. Thinking that the editor may be short of material, I drafted another article for him. But before I submit it I thought I'd have it scrutinized by the sharp-eyed members of this forum. And to avoid the usual energy vs. power units controversy, let me confirm that: (1) energy consumption indicates a flow which is power and therefore the unit is W (2) energy consumed indicates an amount, and when the amount refers to a battery or fuel the unit is J, but when it pertains to time, such as in a day or a year, it is power, thus in W. I trust we agree on that issue. Stan Jakuba
