WebInternal energy is a property. Total Energy (E): The sum of all forms of energy exist in a system. The total energy of a system that consists of kinetic, potential, and internal energies is expressed as: E = U + KE + PE = U + mv 2 /2 + mgz. The change in the total energy of a system is: ΔE = ΔU + ΔKE + ΔPE. WebC p is the heat capacity of water = 1 BTU/lb ºF (given) ΔT = temperature difference = 120 ºF – 55 ºF. Heat energy required to heat 700 gal can be calculated as follows: Heat Required = 5810 lbs x 1 BTU/lb ºF x (120 ºF – 55 ºF) Heat Required = 5810 lbs x 65 ºF Heat Required = 377,650 BTU/week.
