Answer:
1) 0,081 ft/s
2) 0,746 lb/s
Explanation:
The relation between flow and velocity of a fluid is given by:
Q=Av
where:
1)
To convert our data to appropiate units, we use the following convertion factors:
1 ft=12 inches
1 ft3=7,48 gallons
1 minute=60 seconds
So,
[tex]Q=\frac{3,60 gallons}{1 min}*\frac{1min}{60 s}*\frac{1ft3}{7,48gallons}=0,00802 \frac{ft3}{s}[/tex]
As the pipe has a circular section, we use A=πd^2/4:
[tex]d=4,26 inch *\frac{1ft}{12 inch}=0,355ft\\ A=\pi \frac{0,355^{2} }{4}=0,0989ft2[/tex]
Finally:
Q=vA......................v=Q/A
[tex]v=\frac{0,00802ft^{3} /s}{0,0989ft^{2} }=0,081ft/s[/tex]
2)
The following formula is used to calculate the specific gravity of a material:
SG = ρ / ρW
where:
then:
ρ = SG*ρW = 1,49* 62,4 lb/ft3 = 93 lb/ft3
To calculate the mass flow, we just use the density of the chloroform in lb/ft3 to relate mass and volume:
[tex]0,00802 \frac{ft3}{s}*\frac{93lb}{1ft3}=0,746lb/s[/tex]
