Common Abbreviations
KW = Killowatts
Gal = Gallons
in = Inches
SpH = Specific Heat of Solution
SpW = Specific Weight of solution
ΔT°F = Change in temperature degrees Fahrenheit
ΔT°C = Change in temperature,degrees Centigrade
Mins = Heat up time in minutes
Common Equivalents
1 in = 2.54 cm = 25.4 mm = 0.083ft
1 cm = 0.3937 in = 0.0328 ft.
1 in³= 16.39 cm³
1 BTU = 0.2933 watt-hrs
1 KW-Hr = 3412 BTU
Properties Of Water
1 gallon = 231 in³ = 0.1337 ft³ = 3.785L
1 gallon = 8.337 lbs.
1 ft³ = 62.4 lbs. (at 20°C)
specific heat = 1 calorie/gram-°C(at 15°C)
specific heat = 1 BTU/lb.-°F (at 15°C)
specific weight = 8.337 lbs./gallonheat of vaporization = 965 BTU/lb.
Ohm’s Laws
Volts = Amperes x Ohms
Watts = (Amperes)² x Ohms
Amperes = Watts / Volts
Amperes/Phase =(Watts / Volts) x 0.578
(Assuming Balanced 3-Phase Load)
