🔍 Key Concepts

• How viscosity is measured for fuel and lubricating oils • Difference between flash point, pour point, and viscosity tests • Purpose of a timed flow of a fixed volume (e.g., 60 c.c.) through a small orifice

💭 Think About

• Look at the central tube and the 60 c.c. beaker: what property of the oil would be determined by measuring how long it takes that known volume to pass through a small opening? • Which of the four options is normally determined by heating the oil in a cup and introducing an ignition source, and does this match the apparatus shown? • Which property is concerned with how easily the oil will flow at low temperatures, and does that usually require a tall, narrow jar that is tilted rather than a timed flow through an orifice?

✅ Before You Answer

• Identify that the illustration shows a bath with a central tube/orifice and a graduated beaker marked 60 c.c. underneath it • Decide which test method uses time of flow of a fixed volume through a standard opening • Eliminate the choices that normally require a spark/ignition source or cooling and tilting a jar, since those do not match this setup
