Question

When I am trying to calculate the G and GIG the calculate results are different than numbers given why? For example my calculations won’t equal to G= -6760.449 Can someone explain this to me thank you GatP = Psat G 2798.562 (259+273.15)K 6.607k kg K kg kj kg G-6760.449 G at P 1 bar 54-(250+278.15)x.8.083 kJ kg K kg GIG-22626.502 kg ubstituting the values into the equation to calculate the fugacity G-GIG f RT 100 -6760 449- (-22602)10010018015 9 mol In -6760.449-(-22626.502) bar mol K (250+ 273.15) K f 1bar e3648391 bar The result is what is expected i.e. f

Explanation / Answer

dear student,

i have checked all the unit for that G value calculation. i think there must be printing mistake or calculation mistake for answer G=-6760.449

correct answer for G=-717.353 kJ/kg ..

for Gig = -1256.097 kJ-kg

i am sure there is mistake in the given solution because of following point

so just go through my corrected value.
