The kinetic energy of one mole of an ideal gas = 8. The kinetic energy of one molecule of an ideal gas = 1.38 X 10 -23 Joules/degree Kelvin (J/K) Note that Avogadro's Number N A divided by by the atomic mass of an element gives the number of atoms of that element in one gram. The number of atoms in 12 grams of carbon-12 = 6.02214179 X 10 23Īlso = The number of entities in a mole of those entities. The amount of electric charge in one mole of electrons N A X e = 9.650 X 10 4 Coulombs/mole (C/mol) The Gray is the dose, the Sievert is the effect of the dose.Ĥπ X 10 -7Newtons/square Ampere (N/A 2) or Henries/metre (H/m)Ī unit representing an amount of substance which contains 6.022 X 10 23 entities (atoms, molecules, ions, electrons etc.)īoltzmann's Constant / Electron Charge = k/e = 8.6 X 10 -5 ElectronVolts (eV) For instance, if a power of 2,500 watts runs for 180 seconds: 2,500 × 180 450,000 joules of energy Divide this answer by the substance's mass, measured in grams. This equation is suitable for mild and stainless. Multiply the wattage acting on the substance by the time it spends acting on it. Note 4: I Sievert = I Gray X Q where the quality factor (Q)is a measure of the magnitude of the damage done by the dose. Using the same example, reaching temperature in 15 minutes (0.25 hrs). The output power MWe is generally only about 30% or 40% of the input power MWt. MWt is the thermal input power developed by the furnace or nuclear reactor. MWe is the more common and represents the electrical output power of the plant. Note 3: The power in MegaWatts of an electricity generating plant may be expressed as MWe or MWt (alternatively MWth). The rest is lost as heat See Energy Efficiency. An incandescent light bulb typically converts less than 10% of its input electrical energy into light. It is not the light flux produced by 1 Watt of electricity. ![]() Note 2: A light flux of 668 Lumens is equivalent to an energy flow rate of 1 Watt of radiant electrical (or other) power. The amount of oil consumed in producing 11.6 MWh of electrical energy may be more than three times as much due to the inefficiency of the conversion process. It is not the quantity of oil necessary to produce 11.6 MWh of electricity. The enthalpy - or internal energy - of a substance is a function of its temperature and pressure. ![]() Note 1: 1 toe is the quantity of oil which has the equivalent energy content of 11.6 MWh of electricity.
