Steam Mollier diagram for

Estimate steam flow. Refer to the Mollier diagram for steam in Figure 14-21, which shows the available enthalpy in Btu/lb of steam. 

The H-S plot is called a Mollier diagram and is particularly useful in analyzing throttling devices, steam turbines, and other fluid flow devices. A Mollier diagram for steam is presented in Figure 2-37 (standard engineering units) and in Figure 2-38 in SI units. 

Dear engineering reader, please recover from your desk drawer, your steam tables. In the back, there will be a Mollier diagram for steam. Figure 17.2 is a representation of your Mollier diagram. We will use...

From Illustration 2.3-3 we have that H(T, Tj) = H(T, P2) for a Joule-Thomson expansion. On the Mollier diagram for steam, Fig. 2.4-la, the upstream and downstream conditions are connected by a horizontal line. Thus, graphically, we find that T 383 K. (Alternatively, one could also use the Steam Tables of Appendix III.)...
