Answer:
d) 56.16Ib/ft^3[
Explanation:
the specific weight is understood as the weight ratio of a body or fluid per unit volume, to find it we must multiply the density by gravity, using the following ecuation:
γ=ρg
where
ρ=density=0.9g/cm^3=900Kg/m^3
g=9.81m/s^2
γ=(9.8)(900)=8820N/m^3
finally we use conversion factors to convert to lb / ft ^ 3
γ=[tex]\frac{8820 N}{m^{3} }*\frac{m^{3} }{(3.28ft)^{3} } *\frac{1Lb}{4.44N} =56.16Ib/ft^3[/tex]
the especific weight of the fluid is d)56.16Ib/ft^3
