Question

Given that a fluid at 260°F has a kinematic viscosity of 145 mm^2/s, determine its kinematic viscosity in SUS at 260°F.

Answer 1

kinematic viscosity in SUS is = 671.64 SUS

Step-by-step explanation:

given data

kinetic viscosity = 145 mm^2/s

we know

1 mm = 0.1 cm

so kinetic viscosity in cm is
`\\u =145 (0.1)^(2) =1.45 cm^(2)/s`

other unit of kinetic viscosity is centistokes

`1 cm^(2)/s = 100 cst`

so 1.45 cm^2/s will be 145 cst

if the temperature is 260°f , then cst value should be multiplied by 4.632. therefore kinematic viscosity in SUS is = 4.362 *145 = 671.64 SUS
