Can the hydraulic system you designed power a gurney through Guatemala?

What is the viscosity of hydraulic fluid with a kinematic viscosity
index of 300 and that is exposed to a temperature of 50 degrees Farhenheit?
You and your team are creating an adjustable hospital gurney to be used in a medical clinic in Guatemala. The gurney can be raised or lowered thanks to the hydraulic system you designed. However, the surgical team has decided to go a step further, and will be taking the gurneys to remote villages in the mountains where it can easily drop to 50o
F. If you are using a hydraulic fluid with a kinematic viscosity index of 300, what is the viscosity at this temperature (in units of mm2
/s)? This is important because if the fluid is too viscous, your gurney won’t work!
(Hint: You can calculate this using the Walther equation)
