Power CalculatorsCalculate the power required in Kilowatts (kW) to maintain water temperature using the flow rate in gallons or liters per minute (gpm or lpm) and temperature change required in degrees Centigrade (ºC) or Fahrenheit (ºF).
Temperature CalculatorCalculate the temperature change in degrees Centigrade (ºC) using the power available in Kilowatts (kW), the heating time in minutes (Mins), and volume of water in gallons (Gal).
Time CalculatorsCalculates the heating time in minutes (Mins) using the volume of water (Gal), the temperature change required in degrees Centigrade (ºC) or Fahrenheit (ºF), and the power available in Kilowatts (kW).
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.
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
Volts = Amperes x Ohms
Watts = (Amperes)² x Ohms
Amperes = Watts / Volts
Amperes/Phase = (Watts / Volts) x 0.578
(Assuming Balanced 3-Phase Load)
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
