The adiabatic head of a blower is defined as
M k-l[r
where R is the universal gas constant, T is the absolute blower suction
temperature, k is the specific heat ratio, Pr is the ratio of the blower
discharge and suction pressures, and M is molecular weight of the coolant
gas.
If the blower suction temperature is assumed to be the same for
helium and carbon dioxide and equal to 483F, the above equation, evaluated
for both helium and carbon dioxide, gives
5.0192 (p0.39878 _-) + =p0.18194
r, He r, C02
Table 1.11 and Fig. 1.14 describe the thermal and dynamic performance
of the IDCR if the helium coolant were replaced with carbon dioxide.
