Heat Q is energy transferred between the system and the environment as they interact. The units of Q are Joules. Temperature T is a state variable that quantifies the “hotness” or “coldness” of a system. A temperature difference is required in order for heat to be transferred between the system and the environment.

Since nothing is said about the exchange of work, suppose there is only hydrostatic work. Solution The work – PdV is zero if V is constant. The heat is dQ = dU + PdV = dU and we get Q = ∫dU = U 2 – U 1 = U(T T 2,V 1) – U(T T1,V 1). We must know U as a function of T at constant V. 1.6 The second law of thermodynamics Exercise 1.6.1

Algebraic expressions for the correction factor Fhave been developed for vari- ous shell-and-tube and cross-flow heat exchanger configurations [1–3], and the results may be represented graphically. Selected results are shown in Figures 11S.1 through 11S.4 for common heat exchanger configurations.

Thermodynamics is the study of how heat moves around in ‘macroscopic’ objects. Through-out these lectures, we will talk a lot about laws and models. Models are a simplified, empirical description of a real system which generally develops overtime as our knowledge progresses.
