1. How does API gravity (in degrees) relate to density (as measured by specific

gravity)? to viscosity?

API caøng lôùn thì maät ñoä caøng nhoû vaø ngöôïc laïi maät ñoä caøng lôùn khi API caøng nhoû

Ñoä nhôùt bieåu hieän ôû söùc caûn dòch chuyeån cuûa phaàn töû daàu khí di ñoäng

Ñoä nhôùt caøng cao thì API caøng nhoû vaø ngöôïc laïi API caøng cao thì ñoä nhôùt caøng

nhoû
