Web(3,412 Btu/kWh÷heat rate) × 100 = % thermal efficiency of a power plant Because of the inverse proportionality to efficiency, it follows that higher heat rate power plant is undesirable. Three factors determine the heat rate of a plant: Electric Power Output, Operating Conditions and Plant Design. WebDensity of work piece - (Measured in Kilogram per Cubic Meter) - The Density of work piece is the mass per unit volume ratio of the material of workpiece. Rate of Heat Gen in Secondary Shear Zone - (Measured in Watt) - The Rate of Heat Gen in Secondary Shear Zone is the rate of heat generation in the area surrounding the chip-tool contact region. ...
