What Math Conversions Do You Need?

 What math conversions can I add to www.fast-math.org to help people
with home power calculations?
Tnx,

You might add some stuff from that Oklahoma wind site on the effects
of altitude and average-to-Rayleigh windspeed estimation, so Graham
can use more realistic numbers in his gloomy ignorant pontifications :-)

 1. Converting meter disc turns to average watts would be one.  Formula:  (Turns
* Kh
factor)/time in hours = average power over the timing interval.

2. Input start, ending date and time and start and ending kWh reading, compute
average watts, total net kWh, kWh per day, kWh per week, kWh per month.

3. Input average power draw in watts, utility rate in cents/kwh, duty cycle,
compute
the cost per day, week, month.

4. Input indicated power draw over a short interval in watts, kWh consumed over a
specified interval long enough to accumulate many duty cycles, utility rate,
compute
average power, duty cycle, cost per day, week, month.  This is an extrapolation
and
will be less accurate than the above calculations but will take much less time to
data record.

5. Input from the power bill start kWh, end kWh, billing interval, aux charges
(meter
charge, fuel adjustments, etc), compute rate in cents/kWh (both gross and net -
remove aux charges before computing), net kWh used.

6. This one would be a bit more involved because it would require wire tables be
programmed into the solver.  Input volts, amps, PF, wire gauge, wire type (solid,
stranded, etc), utility rate, length of branch, compute voltage drop, watts lost
to
I^2R loss in the wire, cost of watts lost in wire per month, watts, cost saving
if
the PF is corrected to 1.0 at the load and resistance per foot and 100 feet.

I can probably think of some more, given a little time to think about it.
