The formula of specific gravity:
= Specific weight of liquid/ specific weight of pure water at standard temperature.
The specific weight of water =9.81 KN/m^3.
Then according to formula:
7.85/9.81 = 0.8 Ans.
= Specific weight of liquid/ specific weight of pure water at standard temperature.
The specific weight of water =9.81 KN/m^3.
Then according to formula:

Specific gravity or relative density = W1/W2.
W1 = specific weight of given liquid = 7.85 KN/m3.
W2 = specific weight of standard liquid (Water) = 9.81KN/m3.
W1/W2 = 7.85/9.81 = 0.8.
W1 = specific weight of given liquid = 7.85 KN/m3.
W2 = specific weight of standard liquid (Water) = 9.81KN/m3.
W1/W2 = 7.85/9.81 = 0.8.

Specific weight = 7.85kn/m^3,
The density of water = 9.81,
weight/volume,
7.85÷9.81 = 0.8anwser.
The density of water = 9.81,
weight/volume,
7.85÷9.81 = 0.8anwser.

7.85*10^3/9.81*10^3 = 0.8.

Specific weight of oil/specific weight of water.
I) SPECIFIC WEIGHT OF WATER = 9.81 KN/m3.
7.85 /9.81 = 0.8 unit less.
I) SPECIFIC WEIGHT OF WATER = 9.81 KN/m3.
7.85 /9.81 = 0.8 unit less.
