Turbine Efficiency Part 3

Introduction to Heat Transfer Define the term heat transfer. Identify the three forms of heat transfer. Identify factors that affect conduction heat transfer that affect convection heat transfer and that affect radiation heat transfer. Determining Heat Transfer Rate Describe the two formulas that can be used to determine the rate of heat transfer when the process involves a change in temperature. Describe the formula used to determine the rate of heat transfer when there is no change in temperature during the process only a change in enthalpy. Determining the Effect of Heat Transfer Problems Determine the rate of heat transfer for a typical economizer. Describe how changes in the condition of an economizer can affect the rate of heat transfer and plant efficiency. Determine the rate of heat transfer for a typical condenser. Describe how changes in the condition of a condenser can affect the rate of heat transfer and plant efficiency.
