$$ T_d,is = T_s \left( \fracP_dP_s \right)^\frac\kappa-1\kappa = 293 \times 5^\frac0.41.4 = 293 \times 1.584 = 464 \text K $$
With the development of more advanced mathematical models, performance calculation became a crucial step in screw compressor design. Engineers could now predict how a compressor would perform under various operating conditions, such as: kinetic energy of turbulence
The male (driving) and female (driven) rotors consist of helical lobes. The cross-section of these lobes is defined by a series of curves (segments of circles, cycloids, or elipses). kinetic energy of turbulence
