Practical Example
Displacement: Determine the Density of Samples of a Solid Using the Displacement Method.
Reference Liquid: Ethylene glycol. Temperature: 23°C (73.4 °F). Set the density at 20°C (68°F) to 1.113 g/cm
2
and the volume expansion coef-
ficient at 20°C (68°F) to 0.00064 grd
–1
.
Settings (changes in the factory settings required for this example):
Setup: App: Application 1: Density: Method: Displacement
Setup: App: Application 1: Density: Liquid for buoyancy: User-definable
