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:

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
