Thermodynamics
In a centrifugal compressor, air is compressed at a rate of 55kg / min, from a pressure of 101.3Kpa to 6.5 bar. During the process of the form PVk = C, where the isentropic exponent k = 1.4 and C is a constant. Due to compression the air temperature increases by 22⁰C, up to a value t2 = 118⁰C
If the ambient temperature is 22⁰C, calculate:
a) The minimum power required to run the compressor
b) The real power, if its thermal efficiency is: η = 0.84
Consider, V₁≈0, V₂ = 37m / s; ∆Potential≈0
c) Determine the volume ratio (V2 / V1)
