H2O Properties

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.

Abbreviations

KW = Killowatts

Gal = Gallons

In = Inches

Mins = Minutes

SpH = Specific Heat of Solution

SpW = Specific Weight of solution

ΔT°F = Change in degrees Fahrenheit

ΔT°C = Change in degrees Centigrade

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

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)
