SPECIFIC HEAT VALUES

Water’s specific heat is 1.0 BTU, and in order to raise it 1 degree we multiply it by its weight – 8.34. Thus, 1x8.43 = 8.34. Therefore, it takes 16.68 Btu’s to raise water 2 degree in temperature- 2 x 8.43 = 16.68.  If water is 40 degrees and we want to raise it to 160 degrees and to raise water one degree, we multiply the weight times the intended difference in temperature.

Water’s specific heat is 1.0

Intended temperature is 160° - 40° = 120° temperature difference.

120 x 8.34 = 1.000.8 BTU’s are required per gallon.

6 gallon = 6,005 Btu’s

10 gallons = 10,008 Btu’s

15 gallons = 15,012 Btu’s

20 gallons = 20,016 Btu’s

30 gallons = 30,024 Btu’s

True Green Heating Fluid’s specific heat is 0.425.

Intended temperature is 160° - 40° = 120° temperature difference.

120 x 0.425 = 51 BTU’s are required per gallon.

6 gallons = 306 But’s

10 gallon = 510 Btu’s

15 gallon = 765 Btu’s

20 gallon = 1,020 Btu’s

30 gallon = 1,530 Btu’s

                                        Let’s look at another scenario:

Water recovery: 140° needs to be reheated to 160°

20 x 8.34 = 166.8 Btu’s required per gallon.

6 gallons = 1,001 Btu’s

10 gallons = 1,668 Btu’s

15 gallons = 2,502 Btu’s

20 gallons = 3,336 Btu’s

30 gallons = 5,004 But‘s

Fluid recovery: 140° needs to be reheated to 160°

20 x 0.425 = 8.5 Btu’s required per gallon.

6 gallons = 51 Btu’s

10 gallons = 85 Btu’s

15 gallons = 128 Btu’s

20 gallons = 170 Btu’s

30 gallons = 255 Btu’s
