where h1 is the suction enthalpy, h2 is the discharge enthalpy, P1 is the suction pressure, P2 is the discharge pressure, s is the constant entropy at both the suction and discharge, R is the ideal gas constant, T1 is the suction temperature, and γ is the ratio of specific heat capaci...
The behavior of real gases is considered by the specific gas constant Rs and by the compressibility factor z [182,183]. Besides the pressure ratio between inlet pressure pin and discharge pressure pout as well as the inlet temperature Tin, the enthalpy difference Δℎs also depends on the ...
(5 points) – mean and variation in results – discharge, velocity and contraction coefficients must be smaller than unity – if not, give explanation for the non-physical values – discussion of sources of error (unsteadiness, extent of valve opening, measurement of shooting range) Lecture 22 ...
