A liquid flows through a pipe with $3$ sections, each having a different inside diameter as shown above.

Given:

The density of water is $62\mathrm{.}4lb\frac{m}{f}t3$

The specific gravity of the fluid is $0\mathrm{.}9$

The flowrate of the liquid is $140gpm$

The section inside diameters are: $A=0\mathrm{.}75$ in ; $B=2\mathrm{.}25$ in ; $C=3$ in

What is the volumetric flow, $ft\frac{3}{s},$ through the pipe?

What is the velocity, $f\frac{t}{s},$ in section $A?$

What is the velocity, $f\frac{t}{s},$ in section $B?$

What is the velocity, $f\frac{t}{s},$ in section $C?$

What is the mass flowrate, $lb\frac{m}{h}r,$ through the pipe?
