BBQ Propane Tanks - 2012-12-17
BLUE RHINO Tank Exchange $20 each for 16# and 14#
1 gallon of propane weighs 4.24 pounds
A "full" 20 lb cylinder should have 4.7 gallons of propane in it
Propane = 91,502 BTU/gallon / 3412BTU/kwhr = 26.8 Kwhr/gallon ~~$4.02/gallon electrical equivilent - so any propane less than $4/gallon is cheaper than electric
A FULL tank should weight 20 pounds PLUS the Taire Weight (listed on tank as TW-##)
Above $20 tanks held 16# an 14# (Each weighed total 32#, one w/ TR=16 and one TR=18)
16# = 345,660 BTU = 101 Kwhr = $19.99/101 = $.198/Kwhr
14# = 302,453 BTU = 89 Kwhr = $19.99/89 = $0.225/Kwhr
20# = 432,075 = 127 Kwhr = $19.99/127 = $0.157/Kwhr
SO..... It is CHEAPER to use ELECTRICITY, even if propane was 100% efficient, AND I got 20#
BUT U-Haul sells for $3.99/gallon which is cheaper than Rhino
$3.99/gal /26.8Kwhr/gal = $0.149/gallon, same price as Electric, more or less.

Aproximate conversion from celsius to farenhieght
C*2 + 32 (for each 10 over 0 subtract 2 degrees)
The last step makes it exact =>
C*2 + 32 - .2*C = EXACT
(C*2)*(1-.1) + 32 = EXACT [2*C - 10% + 32]
OR (C+15)*2 - this is fairly close
This is not as close at freezing

GEOMETRIC FORMULAS
CIRCLE center at origin x^2 + y^2 = r^2
center at (h,k) (x-h)^2 + (y-k)^2 = r^2
PARABOLA Y=X^2/(4f) f = focal length
or y= ax^2 + bx +c
radius of curvature near center R = X^2/(2Y)
Radius of Curvature at any point R(X)
R(X) = 2f(1+[X/2f]^2)^1.5 How to calculate the locus of R(X)?
-One of the interesting things about a focal
point is that the distance across the parabola
through the focus is equal to four times the
distance from the focus to the vertex. so
when Y = focal length, X = 2*Y or diameter of
a parabolic dish = 4 times focal length if as
deep as focal length

units commonly used for Earth orientation:
1 mas = 1 milliarcsecond = 1 thousandth of a second of arc (for polar motion & nutation);
1 ms = 1 millisecond = 1 thousandth of a second of time (for UT1);
1 mas equals an equatorial shift at the Earth's surface of 3.1 cm;

-Distance to Sun = 149,000,000 KM ~ 93,000,000 miles
-Diameter of sun = 1,390,000 KM ~863,706 miles
a reflection will grow about 1% of distance so a 1 meter mirror will look like 3 meters at 300 meters away. ???
=Angle to outer edges of sun.
-Moon orbits earth ~238,000 miles ~ 382,900 km
-Liquid spun at ω to get a parabola
The shape of the surface is given by z = (ω^2/2g)r^2. This is a parabola with focal length f = g/2ω^2
=focal length f of a rotating liquid turns out to be f = g/2(ω)^2
g is the acceleration of gravity
ω is the angular velocity (radians per second) of the liquid.
