Chloroform flows through a 4.26 inch inside-diameter pipe at the rate of 3.60 gallons per minute. what is the average velocity of chloroform in the pipe? number ft/s the specific gravity of chloroform is 1.49. what is the mass flow rate of the liquid for the conditions described above?

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,

As the pipe has a circular section, we use A=πd^2/4:

Finally:

Q=vA......................v=Q/A

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:

so what is the problem with your lab report and whats the subject of the lab report? i will you

you did not give any options thus this is the best answer i can give to you with this little information you have given

> they are both natural and not man made

> they can be tracked and predicted by the right tools
