WebFeb 15, 2024 · Polytropic Process can be defined as the process in which heat absorbed by the gas due to unit rise in temperature is constant. A polytropic process is a thermodynamic process that can be expressed using the following equation. PVn=C, It is a Polytropic process equation. Where, P is the pressure. V is the volume. WebApr 20, 2024 · Changes in MW, polytropic head, speed and power are highlighted in yellow. Inlet volume (orange highlight) is almost constant. Compressor suction and discharge pressures are also constant. Compressor power, being product of polytropic head and weight flow rate, does not change significantly due to decrease in weight flow rate with MW. WebThere's the isometric process, also known as isochoric or isovolumetric, where the change in volume is 0, which meant, remember, that means no work can be done. The work was also 0 for an isometric process. And then there's the adiabatic process where no heat is allowed to flow into or out of the system. citb northern ireland website
