: : : oil viscosity is the measurement of oils ability to:
: : : a,flow freely
: : : b,flow when heated
: : : c,withstand pressure
: : : d,with stand heat
: : : all you retired chiefs come out of hiding and help with this question
: : Viscosity changes with temperature so at different temperatures the an oils viscosity is different so its not b. Viscous resistance is independent of pressure so its not c. Definitely not d. The answer is A, however, like Bill Clinton you may ask what definition of freely are you using. Some test of viscosity actually measure how long it takes a fluid to flow down a slope or through an oriface.
