Question

Given an oil has a kinematic viscosity of 380 centistokes. Find its absolute viscosity in centipoise (cp). Assume a specific gravity of 0.89.

a) 426.70 cp
b) 339.20 cp
c) 470.80 cp
d) 254.60 cp

Answer 1

To find the absolute viscosity in centipoise, multiply the kinematic viscosity by the specific gravity. In this case, the absolute viscosity is 339.20 cp.

Step-by-step explanation:

Viscosity is a measure of a fluid's resistance to flow. The absolute viscosity, also known as dynamic viscosity, is measured in centipoise (cp). To find the absolute viscosity in centipoise, you can use the equation: absolute viscosity (cp) = kinematic viscosity (centistokes) x specific gravity.

In this case, the kinematic viscosity is given as 380 centistokes and the specific gravity is given as 0.89. So, the absolute viscosity can be calculated as follows:

To find the absolute viscosity in centipoise (cp) of an oil with a kinematic viscosity of 380 centistokes and a specific gravity of 0.89, we can use the formula:

Absolute viscosity (cp) = 380 centistokes x 0.89 = 338.2 cp.

Therefore, the correct answer is b) 339.20 cp.
