Answer:
The minimum volume requirement for the granite stones is 1543.64 cm³
Explanation:
1 granite stone weighs 10 denarium
100 granted stones will weigh 1000 denarium
1 denarium = 3.396g
1000 denarium = 3396g.
But we're told that 20% of material is lost during the making of these stones.
This means the mass calculated represents 80% of the original mass requirement, m.
80% of m = 3396
m = 3396/0.8 = 4425 g
This mass represents the minimum mass requirement for making the stones.
To now obtain the corresponding minimum volume requirement
Density = mass/volume
Volume = mass/density = 4425/2.75 = 1543.64 cm³
Hope this helps!!!
Answer:
the difference in pressure between the inside and outside of the droplets is 538 Pa
Explanation:
given data
temperature = 68 °F
average diameter = 200 µm
to find out
what is the difference in pressure between the inside and outside of the droplets
solution
we know here surface tension of carbon tetra chloride at 68 °F is get from table 1.6 physical properties of liquid that is
σ = 2.69 ×
N/m
so average radius =
= 100 µm = 100 ×
m
now here we know relation between pressure difference and surface tension
so we can derive difference pressure as
2π×σ×r = Δp×π×r² .....................1
here r is radius and Δp pressure difference and σ surface tension
Δp =
put here value
Δp =
Δp = 538
so the difference in pressure between the inside and outside of the droplets is 538 Pa
