Question

Calculate desity, Speafic weight and weight of 1
petrol of Spefic gravity
0.7
​

Answer 1

Answer:

given,

1) specific gravity of petrol is 0.7,

specific gravity is defined as the ratio of the density of given fluid to the density of standard fluid(water),

therefore,

s = density of petrol / density of water,

=> 0.7 = density of petrol / 1000,

=> density of petrol = 0.7*1000 = 700 kg/m^3,

Density is also defined as mass acting per unit volume,

2)specific weight is given by the ratio of weight acting per unit volume,

w = mg/ v,

=> w = Pg,

=> w = 700*10,

=> w = 7000 N/m^3
