Question

The specific weight of sea water is 10.1 kN/m^3. Convert to lbs/in^3.

Answer 1

0.03719 lbs/in³

Step-by-step explanation:

Specific weight is given by multiplying the density of an object to the acceleration due to gravity.

`\gamma =\rho g\\\Rightarrow \rho=(gamma)/(g)\\\Rightarrow \rho=(10.1* 10^3)/(9.81)\\\Rightarrow \rho=1029.562\ kg/m^3`

`1\ kg=2.20462\ lb`

`1\ m=39.3701\ in`

`\\\Rightarrow 1029.562\ kg/m^3=(1029.562* 2.20462)/(39.3701^3)=0.03719\ lbs/in^3`

So,

`10.1\ kN/m^3=0.03719\ lbs/in^3`
