Table 88 

 ISOBARIC SPECIFIC HEAT RESIDUAL OF MOIST AIR 



(Further explanation on p. 331.) 

 The isobaric specific heat residual Ac p of moist air is defined by 



c P =|R[l + |(rA)] + Ac, 



339 



= 0.2399 + 0.4409r + Ac p (13) 



where c p is derivable from the Goff-Gratch formulation by means of the identical rela- 

 tion, c p = (3/i/9r) p> r . Values are listed in Table 88 as a function of pressure p, tempera- 

 ture t, and relative humidity U. In the range covered by this table the isobaric specific 

 heat residual lies between —0.0009 and +0.0068 ITcal. "K." 1 (gram dry air)" 1 .
