What is the weight in pounds of a gallon of oil that has a specific gravity of .86

Andreyy89

Answer:

Mass of oil will be 7.176 pound

Explanation:

We have given specific gravity of oil = 0.86

We know that specific gravity is given by $specific\ gravity=\frac{density\ of\ oil}{density\ of\ water}$

$0.86=\frac{density\ of\ oil}{1000}$

Density of oil = $860kg/m^3$

We have given volume of oil = 1 gallon

We know that 1 gallon = 0.003785 $m^3$

So mass of oil = volume ×density

mass = 0.003785×860 = 3.2551 kg

We know that 1 kg = 2.2046 pound

So 3.2551 kg = 3.2551×2.2046 = 7.176 pound

A surface grinding operation is used to finish a flat plate that is 5.50 in wide and 12.500 in long. The starting thickness is 1

valina [46]

Answer:

77.40

Explanation:

Initial width = 5.5 Inches

Initial length = 12.5 inches

Initial thickness = 1.085 inches

After grinding

Thickness of flat plate = 1 inch

Grinding wheel

starting diameter( di )= 6.013 inches

width of grinding wheel = 0.5 inch

After operation

Diameter of grinding wheel ( df ) = 5.997

Calculate the grinding ratio in this operation

First step : determine the volume of material removed from flat plate

= Length of flat plate * width of flat plate * change in thickness

= 12.5 * 5.5 * ( 1.085 - 1 )

= 5.8437 in^3

Volume of material from grinding wheel

= π / 4 * ( di^2 - df^2 ) * width

= π / 4 * ( 6.013^2 - 5.997^2 ) * 0.5

= 0.0755 in^3

Finally the Grinding ratio

= 5.8437 / 0.0755

= 77.4
