Answer:
speed by mass attain is 55.86 m/s
Explanation:
given data
glucose = 10 g
mass = 100 kg
to find out
speed by mass attain
solution
we know glucose have 180 g molecular weight and
that 1 g glucose produce energy = 2816/180 × 10³ J
so here 10 g of glucose produce energy = 1.56 ×
J
so here energy release = 1/2 × mv²
1.56 ×
= 1/2 × (100)v²
v² = 3.12 × 10³
and v = 55.86 m/s
so speed by mass attain is 55.86 m/s

Solution :
Given :
External diameter of the hemispherical shell, D = 500 mm
Thickness, t = 20 mm
Internal diameter, d = D - 2t
= 500 - 2(20)
= 460 mm
So, internal radius, r = 230 mm
= 0.23 m
Density of molten metal, ρ = 
= 
The height of pouring cavity above parting surface is h = 300 mm
= 0.3 m
So, the metallostatic thrust on the upper mold at the end of casting is :

Area, A 




= 7043.42 N
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
False! Just saying. You could be under the influence, or just have no clue as to what you're doing.
