Mechanisms of heat transfer

Heat transfer is an essential discipline in thermal engineering that deals with the transfer, conversion, usability, and creation of heat or thermal energy. Transfer of heat occurs through various mechanisms like conduction, convection, radiation, and change of phases. All these mechanisms have distinct characteristics, but these mechanisms can simultaneously occur in an identical system.

9.16. One kind of thermodynamic diagram that is useful in engineering problems is the P–H diagram, in which the x-axis is molar enthalpy and the y-axis is pressure.(a) Several kinds of iso-lines can be drawn in such a diagram, including isotherms(constant temperature), isentrops (constant entropy), and isochores (constant molar volume). For each of these three cases, find expressions for the slope of these lines on a P–H diagram in terms of measurable properties.(b) Find expressions for these slopes for the ideal monatomic gas, in terms of T and P.
