Work: Calculate the value of equation (1.4*287/0.4)*ln(0.957/0.8333)-287*ln(0.4/0.5283) .
Question type: Mathematical calculation
Solution:
(1.4*287/0.4)*ln(0.957/0.8333)-287*ln(0.4/0.5283)
=1004.5*ln(0.957/0.8333)-287*ln(0.4/0.5283)
=1004.5*ln1.148446-287*ln(0.4/0.5283)
=1004.5*ln1.148446-287*ln0.757146
=1004.5*0.13841-287*ln0.757146
=1004.5*0.13841-287*-0.278199
=139.032845-287*(-0.278199)
=139.032845-(-79.843113)
=218.875958
Answer:(1.4*287/0.4)*ln(0.957/0.8333)-287*ln(0.4/0.5283)=218.875958
