Which of the following viscosity scales measures kinematic viscosity?

Question 1 of 27070

Which of the following viscosity scales measures kinematic viscosity?

🔍 Key Concepts

• Difference between kinematic viscosity and absolute (dynamic) viscosity • Units used for kinematic viscosity in lubrication (especially metric units) • Which listed scales are actually time tests (seconds to flow through an orifice) vs a direct viscosity unit

💭 Think About

• Ask yourself: which option is expressed as a true viscosity unit (like area per time), not just a flow time? • Consider which scales are commonly used on lubrication oil data sheets to describe kinematic viscosity at 40°C and 100°C. • Think about which of these relate to standardized orifice flow tests (measured in seconds), rather than a physical property unit.

✅ Before You Answer

• Identify which option is in units of mm²/s (even if written differently). • Separate the choices that are ‘seconds’ flow-time scales from the one that is not. • Recall which designation is used in most ISO/ASTM kinematic viscosity charts for marine lubricants.
