Admirals Sign Ian White to PTO. The Admirals announced today that they have signed veteran defenceman Ian White to a Professional Tryout Contract (PTO). Ian White is an NHL veteran with over 500 games and (45-134) 179 points.
Also a polytropic compression process like gas through a centrifugal compressor where heat loss from the compressor (into environment) is greater than the heat added to the gas through compression. â. is the isentropic exponent, yielding an isentropic process (adiabatic and reversible).
An adiabatic process can be either reversible or irreversible. In the case of the reversible adiabatic process, the entropy of the system remains constant. A reversible adiabatic process is therefore called isoentropic. On a phase diagram of the system it is represented by an adiabatic curve or by an isoentropic curve. In an irreversible adiabatic process the entropy increases.
