An operating parameter often used by power plant engineers is the heat rate. The heat rate is defined as,

where Qboiler is the heat transfer rate (Btu/h) to the water in the boiler due to combustion of a fuel and Wnet is the net power (kW) delivered by the plant. In comparison, the thermal efficiency of the power plant is defined as,

where the numerator and denominator have the same units. Consider a power plant that is delivering 1000 MW of power while utilizing a heat transfer rate of 3570 MW at the boiler. Determine the heat rate and thermal efficiency of this power plant.
