Souza Marques	Comparison between the Wilhelmy surface tension measurement method and the pendant drop shape analysis method	2025	6	.pdf	application/pdf	3483	170	46	This comparison involved surface tension measurements of these liquids: bidistilled water, n-dodecane, and per- fluorocarbon (FC-40), these liquids were chosen to cover a wide range of surface tension with stability Surface tension measurement by the pendant drop shape analysis method The calibration data include the regression for obtain- ing the surface tension in mN m−1 in the temperature range from 18 °C to 30 °C and the surface tension mea- surement range was from 16 mN m−1 to 73 mN m−1 with an expanded uncertainty of 0.28 mN m−1 and a coverage factor k = 2.00, according to: γc = C0 + C1 · TL + C2 · γi, (3) where γc is the corrected surface tension, in mN m−1; γi is the indicated surface tension, in mN m−1; C0, C1 and C2 are the parameters of the regression equation, and TL is the measurement temperature, in °C.	cache/ap-10038.pdf	txt/ap-10038.txt
