A fluid flows through a pipe of constant circular cross-section diameter 1.1m with a mean velocity of 50cm/s. The mass flow rate of the flow through the pipe, given by the formula mass flow rate = (density) (mean velocity) (cross - sectional area), is measured to be 110 kg/s. Find the specific gravity, specific weight and specific volume of the fluid.

Answer:

Explanation:

Given

diameter(d)=1.1 m

mean velocity(u)=50 cm/s

mass flow rate(m)=110 kg/s

[tex] A=0.950 m^2[/tex]

[tex]m=\rho \cdot A\cdot u[/tex]

where [tex]\rho [/tex] =density of fluid

[tex]110=\rho \times 0.95\times 0.5[/tex]

[tex]\rho =231.46 kg/m^3[/tex]

Therefore specific gravity[tex]=\frac{\rho }{\rho _{water}}[/tex]

[tex]=\frac{231.46}{1000}=0.231[/tex]

Specific weight[tex]=\rho \cdot g=231.46\times 9.81=2270.70 kg/m^2-s^2[/tex]

specific volume[tex]=\frac{1}{density}[/tex]

[tex]=\frac{1}{231.46}=0.00432 m^3/kg[/tex]
