Does any one have PDF copies of these standards? Thanks

The enthalpy diagrams for refrigerants in the MERM are kind of hard to read and I think ammonia properties are missing.  Does any one have a packet of better charts fir all refrigerants? 

I am looking at problems 27.4 and 27.5 in the MERM companion and they both ask for the thermodynamic efficiency given the pump and turbine efficiency. The answer shows to use the steam tables then find all the enthalpies at all the stages and then find the actual  enthalpies  due to the pump and...

I am going through the MERM practice problems and I am trying to do every one in every chapter.  My plan is to take the HVAC test in April.  I am having a really hard time with the problems in chapter 28 and 29. They are the reciprocating combustion and combustion turbine respectively.  How...

Hi all, When a compressible flow problem gives you a temperature and pressure in the set up, how do you determine if they gave you a static temp or a total temp? I think if the flow is originating in a tank the pressure and temperature of the gas in the reservoir would be considered the total...
