Question

A 40 KN tank weighs 64 KN when filled with kerosene and 70 KN when filled with the same volume of water. Find the specific gravity of kerosene

Answer 1

Specific gravity means the ratio of the mass of object to the mass of the sane volume of water. The answer is 0.8

Answer 2

Answer:

0.8

Explanation:

According to the question,

The weight of water in the tank,

= Total weight - weight of the tank

= 70 - 40

= 30 KN

The weight of Kerosene in the tank,

= Total weight - the weight of the tank

= 64 - 40

= 24 KN

$Specific ~~Gravity ~of ~kerosene =\frac{Specific~ weight ~of ~Kerosene}{Specific ~weight~ of~ water}\\= \frac{24}{30}\\\\= \frac{4}{5}\\\\= 0.8$

Hence, the specific gravity of kerosene is 0.8.
