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:
- Q, flow [ft3/s]
- A, cross section of the pipe [ft2]
- v, velocity of the fluid [ft/s]
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:
- ρ = density of the material [lb/ft3]
- ρW = density of water [lb/ft3] = 62.4 lbs/ft3
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:

Answer:
sodium hydroxide and hydrochloric acid is the reactants
Answer:
Here boron-11 means the name of the element is boron and the mass number is 11
Explanation:
When equilibrium is reached, the solution is said to be saturated. A solution containing a higher concentration of solute than its solubility is said to be supersaturated.
Answer: d
I would see chemical constitution and physical components are not changed.
Because physical reaction won't change the component itself
