Abstract : A research facility was designed and erected to determine the velocity of sound in superheated steam at pressures and temperatures to 5000 psi and 800F. A vibrating quartz crystal was used to set up a series of standing waves in a cylindrical acoustic chamber. Frequency and wave length were determined at steam conditions up to 3400 psi and 719F. Experimental results show close agreement with velocities computed from the 1967 international formulations for steam. Velocity of sound in high pressure steam can be determined more accurately by ultrasonic methods than from calculated values based on currently available tables of thermodynamic steam properties.
