  2. Saybolt universal viscosity - Wikipedia

    en.wikipedia.org/wiki/Saybolt_universal_viscosity

    The Saybolt FUROL viscosity test occurs at 120 °F (49 °C), or more recently, 50 °C (122 °F), and uses a larger calibrated tube. This provides for the testing of more viscous fluids, with the result being approximately 1 ⁄ 10 of the universal viscosity.

  3. Mini-rotary viscometer - Wikipedia

    en.wikipedia.org/wiki/Mini-rotary_viscometer

    The mini-rotary viscometer is a device used to measure the pumpability of an engine oil at low temperatures. [1] [2] Engine oils must meet viscometric standards including those determined by the MRV in order to be classifiable within SAE J300 viscosity grades. The requirement was added after the winters of 1980-81 and 1981-82 caused major ...

    It enables the external test equipment to obtain "pending" diagnostic trouble codes detected during current or last completed driving cycle for emission-related components/systems. This is used by service technicians after a vehicle repair, and after clearing diagnostic information to see test results after a single driving cycle to determine ...

  6. Oil pressure - Wikipedia

    en.wikipedia.org/wiki/Oil_pressure

    Murphy oil pressure gauges with switches that activate on low pressure. Oil pressure is an important factor in the longevity of most internal combustion engines. [1] With a forced lubrication system (invented by Frederick Lanchester), oil is picked up by a positive displacement oil pump and forced through oil galleries (passageways) into bearings, such as the main bearings, big end bearings ...

    Two game wardens found the decomposed remains of a young girl in a wooded area of Lebanon County on Oct. 10, 1973, approximately 47 miles from Brenneman's home in York County, Lacey said.

  8. Pressure head - Wikipedia

    en.wikipedia.org/wiki/Pressure_head

    In many venturis, the column on the left has fluid in it (>), while only the column on the right is a siphon (<). If p < 0 {\displaystyle p<0} and g < 0 {\displaystyle g<0} , we observe that the pressure head is again positive, predicting that the venturi meter shown above would look the same, only upside down.
