The specific gravity of mercury at 80°C is 13.4. Determine its density and specific weight at this temperature. Express your answer in both SI and BG units.

A certain oil flows through a 2.5 in diameter pipe at 60°F with a mean velocity of 6 ft/s. Determine the Reynolds’s number,
, for this flow. The oil has a density of 1.77 slug/f and a dynamic viscosity of 8 X
 lb-s/f .
