The approximate heating value of coal is 3.25 x 104 kj/kg (14,000 btulb). a modern coal-fired power plant rated at 1000 mw(el) requires a thermal input of about 2600 mw from fuel. (a) assuming operation at rated power percent of the time in a calendar year, how many kilograms of coal would be required? (b) if 6.2 percent of the coal used is discharged as ash, what is the annual ash accumulation?

Your answer is 32 hope i  

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.
