· Abstract. An axisymmetric finite element model of heat flow was used to evaluate some of the assumptions inherent in the steady-state heat balance method for measuring sap flow in herbaceous plants. Results indicate that the gauge slightly overestimates conduction up and down the stem when sap flow is nearly zero, causing a

· A high heat rate and low efficiency could mean your power plant isn’t dispatched to the market by a grid operator. To calculate the thermal efficiency of a power plant divide 3,412 BTU by the heat rate. For instance, if a coal power plant has a heat rate of 10,000 BTU/kWh, its thermal efficiency would be 3,412 BTU / 10,000 BTU/kWh or 34%.
