Jobs was named after William Job (1843–1931) who was once one of the most prominent coal company operators in the Hocking Valley. It had several mines, a row of houses, a school and a post office was established in 1890, and remained in operation until 1924. [2] The train station was on the Brush Fork Branch of the Hocking Valley Railway.
Based on a method published in 1931 by H.N.Marsh, [1] a Marsh cone is a flow cone with an aspect ratio of 2:1 and a working volume of at least a litre. A Marsh funnel is a Marsh cone with a particular orifice and a working volume of 1.5 litres.
The higher the viscosity, the larger the damping imposed on the resonator. The resonator's damping may be measured by one of several methods: Measuring the power input necessary to keep the oscillator vibrating at a constant amplitude. The higher the viscosity, the more power is needed to maintain the amplitude of oscillation.
A Mooney viscometer MV 2000 Mooney Viscometer. A Mooney viscometer or rotating disk viscometer is an instrument used for measuring the Mooney viscosity of rubbers. [1] Invented in the 1930s by Melvin Mooney, [2] it contains a rotating spindle and heated dies, the substance encloses and overflows the spindle and the mooney viscosity is calculated from the torque on the spindle.

Transportation and warehousing employs 183,000 Ohioans, amounting to a $12 billion industry, or 3.6% of the GSP. Since 2003, Ohio has added 21,500 logistics jobs. [165] Ohio has the 8th largest highway system, and 4th largest interstate system in the country. Ohio's trucking industry ranks 4th in the nation with a total economic output of $5.2 ...
The proportionality factor is the dynamic viscosity of the fluid, often simply referred to as the viscosity. It is denoted by the Greek letter mu ( μ ). The dynamic viscosity has the dimensions ( m a s s / l e n g t h ) / t i m e {\displaystyle \mathrm {(mass/length)/time} } , therefore resulting in the SI units and the derived units :
