PROPERTIES OF WATER


FAHRENHEIT OR CENTIGRADE (F/C) ? F

INPUT INITIAL TEMP (32-212 F ) = 60

DENSITY (KG/M^3) = 999.016447
DENSITY (#/FT^3) = 62.3665588
DENSITY (#/GAL)  = 8.33716158
SPECIFIC GRAVITY = 0.99904142

CALCULATE VOLUME EXPANSION? Y/N =  Y

INPUT FINAL TEMP (32-212 F ) = 212

VOLUME OF WATER V= 12

DENSITY (KG/M^3) = 958.364855
DENSITY (#/FT^3) = 59.8287628
DENSITY (#/GAL)  = 7.99790902
SPECIFIC GRAVITY = 0.95838881

ORIGINAL VOLUME = 12
FINAL VOLUME= 12.5090119
