I do have those books for sale: 2008 NCEES PE Mechanical Engineering Sample Questions and Solutions $45.0 shipping included 2006 ASHREA Handbook – Refrigeration IP Ed. $55.0 shipping included 2007 ASHREA Handbook – HVAC Application IP Ed. $55.0 shipping included Or all three books for $140.

I have the NCEES PE Mechanical Engineering Sample Questions and Solutions (NCPEM5) - 2008 for $40.

Which one has the right solution? 2001 513 COP= (h2-h1)/(h4-h3) where they get four numbers for the enthalpy ? One of the process is not constant enthalpy? Thank you.

Please let me know if you failed with a 69% or 68% how many problems you did right. Thank you.

Looks like with 40 right you get 65% score.(you think will be 50%) Somebody with 36 right has a 63% failing score. I am just trying to find how far I was to pass the exam.

I'm curious to find out from my 65% diagnostic report how many questions I was short to pass the PE exam. Please check on your scores on the attached excel and let me know if the spreadsheet calculate the percentage right. Thank you. PE_Score.xls

My wife will be happy too, Good luck to everybody.

Q=m*cp*deltaT for water cp=1Btu/lb'F There are 8.33lbH2O/gallon 60 minute/hour Q=GPM *8.33*60 *1*deltaT= 500*GPM*deltaT This is an important formula used all the time when the give you water and GPM

1.09=0.075*0.24*60 ma ,cp, minutes

Check on the equation they say Qcond - condenser and Qevap- evaporator and work done by the compressor plus some friction .

The way I see it is: water enter 100F exit 80F with some vapor (evaporated water) air enter 85F exit 95F and more humid the mass balance of water is: mw2=mw1-(W2-W1)ma Energy balance is: mw1*hf1+ma*ha1=mw2*hf2+ma*ha2 I think they use hf because is water out at 80F sat liquid . If you sent...
