Question

One litre of a certain fluid weighs 8N. What is its specific volume​

Answer 1

Answer:

Specific volume= v/m

V=1*10^-3

m=8/9.81

Now, specific volume = 10^-3/(8/9.81)=(9.81*10^-3)/8 = 1.23*10^-3

Answer 2

Given - Volume and weight

Find - Specific volume

Solution - Specific volume is defined as "the number of cubic meters occupied by one kilogram of a particular substance". Representing this in mathematical expression -

V = v/m. Here, V is specific volume, v is volume and m is mass.

Converting volume to cubic metre. As per the known fact, 1 litre = 10-³ m³.

Weight = mass*acceleration due to gravity

Taking acceleration due to gravity as 10 m/s².

Mass = 8/10

Performing division

Mass = 0.8 kg

Keep the values in formula to find the specific volume.

V = 10-³/0.8

Performing division

V = 1.25*10-³ m³/kg

Hence, the specific volume is 1.25*10-³ m³/kg.
