The ultrasonic speeds in the liquefied fluorocarbon azeotropic mixture refrigerant R502 were measured over the ranges of temperature from 283.15 to 323.15K and pressures from near-saturated vapor pressure to about 50 MPa by using a sing-around technique operated at a frequency of 2 MHz. The results, which showed smooth change with pressure for each isotherm, were used to estimate the values at the saturated liquid. The isentropic compressibilities were determined from experimental values.
