1 centipoise is equivalent to

ANS:C - 2.42 lb/ft.hr

1 centipoise (cP) is a unit of dynamic viscosity, which measures a fluid's resistance to flow. Out of the options provided:

1. 1 centipoise is equivalent to 1 gm/cm.second.
   • This statement is correct. 1 centipoise is equal to 1 gram per centimeter per second (g/cm·s), which is a unit of dynamic viscosity commonly used in the metric system.
2. 1 centistoke
   • Centistoke (cSt) is a unit of kinematic viscosity, not dynamic viscosity like centipoise. They are related but measure different properties. 1 centistoke is not equivalent to 1 centipoise.
3. 2.42 lb/ft.hr
   • This is a unit of viscosity, but it is in pounds per foot per hour (lb/ft·hr), not centipoise.
4. 2.42 lb/ft.second
   • This is a unit of viscosity, but it is in pounds per foot per second (lb/ft·s), not centipoise.
