A percentage increase from 80 to 100 is equal to 25%.
What is a percentage?A percentage can be defined as any number that is expressed as a fraction of hundred (100). This ultimately implies that, a percentage indicates the hundredth parts of any given number.
The types of percentage.In Mathematics, there are two main types of percentage and these include the following:
Percentage decreasePercentage increaseMathematically, percentage increase can be calculated by using this formula:
Percentage increase = [Final value - Initial value]/Initial value × 100
Substituting the given parameters into the formula, we have;
Percentage increase = [100 - 80]/80 × 100
Percentage increase = [20]/80 × 100
Percentage increase = 1/4 × 100
Percentage increase = 25%.

A well-type inclined manometer has a gas pressure difference of 17 cm-of-water at its ports (higher pressure to well). If the manometer is inclined at an angle of 12 degrees and contains water, what is the reading on the manometer (i.e. R)?
Answer:
New reading of water = 81.76 cm² (Approx)
Explanation:
Given:
Pressure difference = 17 cm
θ = 12°
Find:
New reading of water
Computation:
New reading of water = Pressure difference / Sinθ
New reading of water = 17 / sin 12
New reading of water = 81.76 cm² (Approx)
2.) A fluid moves in a steady manner between two sections in a flow
line. At section 1: A2 = 10 ft?, V = 100 fpm, vl = 4 ftp/lb
At section 2: A2 = 2 ft², P2 = 0.20 lb/ft?
Calculate (a.) the mass flow rate, and
(b.) the speed at section 2
Answer:
[tex]250\ \text{lbm/min}[/tex]
[tex]625\ \text{ft/min}[/tex]
Explanation:
[tex]A_1[/tex] = Area of section 1 = [tex]10\ \text{ft}^2[/tex]
[tex]V_1[/tex] = Velocity of water at section 1 = 100 ft/min
[tex]v_1[/tex] = Specific volume at section 1 = [tex]4\ \text{ft}^3/\text{lbm}[/tex]
[tex]\rho[/tex] = Density of fluid = [tex]0.2\ \text{lb/ft}^3[/tex]
[tex]A_2[/tex] = Area of section 2 = [tex]2\ \text{ft}^2[/tex]
Mass flow rate is given by
[tex]m=\rho A_1V_1=\dfrac{A_1V_1}{v_1}\\\Rightarrow m=\dfrac{10\times 100}{4}\\\Rightarrow m=250\ \text{lbm/min}[/tex]
The mass flow rate through the pipe is [tex]250\ \text{lbm/min}[/tex]
As the mass flowing through the pipe is conserved we know that the mass flow rate at section 2 will be the same as section 1
[tex]m=\rho A_2V_2\\\Rightarrow V_2=\dfrac{m}{\rho A_2}\\\Rightarrow V_2=\dfrac{250}{0.2\times 2}\\\Rightarrow V_2=625\ \text{ft/min}[/tex]
The speed at section 2 is [tex]625\ \text{ft/min}[/tex].
(a) The mass flow rate will be "250 lbm/min".
(b) At section 2, the speed will be "625 ft/min".
Speed and MassAccording to the question,
Section 1 area, A₁ = 10 ft²
Section 2 area, A₂ = 2 ft²
Water's velocity, V₁ = 100 ft/min
Volume at section 1, v₁ = 4 ft³/lbm
(a) We know the formula,
Mass flow rate, m = ρA₁V₁
= [tex]\frac{A_1 V_1}{v_1}[/tex]
By substituting the values,
= [tex]\frac{10\times 100}{4}[/tex]
= [tex]\frac{1000}{4}[/tex]
= 250 lbm/min
(2) The speed will be:
→ m = ρA₂V₂
or,
V₂ = [tex]\frac{m}{\rho A_2}[/tex]
By substituting the values,
= [tex]\frac{250}{0.2\times 2}[/tex]
= [tex]\frac{200}{0.4}[/tex]
= 625 ft/min
Thus the responses above are correct.

b. 7 years (EUAC - $672,616)
c. 3 years (EUAC - $904,384)

Explanation:
First cost =$ 1,050,000
Salvage Value =$ 225,000 Maintenance & Operating cost =$ 235,000 Maintenance & Operating Gradient =$ 75,000 MARR =10 %
EUAB - EAUC $=\$ 1,050,000(\mathrm{~A} / \mathrm{P}, 10 \%, \mathrm{n})+\$ 225,000(\mathrm{~A} / \mathrm{F}, 10 \%, \mathrm{n})$
$$
-\$ 235,000-\$ 75,000(\mathrm{~A} / \mathrm{G}, 10 \%, \mathrm{n})

Try $\mathrm{n}=4$ years:
$$
\text { EUAB - EAUC }=\$ 331,275+\$ 48,488-\$ 235,000-\$ 103,575=-\$ 621,362

Try n=6 years
{ EUAB - EUAC }=-$ 241,080+$ 29,160-$ 235,000-$ 166,800=-$ 613,720
Thus, year 5 has the minimum EUAB - EUAC, hence the most economic life is 5 years.

Answer:
10 cents/kwh
Explanation:
Base monthly charge = $10.00
First 100 kwh at $0.16/kwh = $16.00
Next 200 kwh at $0.10/kwh = $20.00
Remaining 400 kwh at $0.06/kwh = $24.00
Total charge = $10 + $16 + $20 + $24 /(100+200+400)
Average cost = $70/700 or 10 cents/kwh

An asphalt concrete mixture includes 94% aggregate by weight. The specific gravities of aggregate and asphalt are 2.65 and 1.0, respectively. If the bulk density of the mix is 147 pcf, what is the percent voids in the total mix
Answer:
2.0%
Explanation:
Percentage of aggregate = 94%
Specific gravity = 2.65
Specific gravity of asphalt = 1.9
Density of mix = 147pcf = 147lb/ft³
Total weight of mix: (volume = 1ft³)
= (147lb/ft³)(1ft³)
= 147lb
Percentage weight of asphalt in mix:
100% - 94%
= 6%
Weight of asphalt binders
= 6% x 147lb
= 8.82lb
Weight of aggregate in mix:
= 94% x 147
= 138.18lb
Specific weight of asphalt binder:
(Gab)(Yw)
Yw = specific Weight of water
= 62.4lb
Gab = specific gravity of asphalt binder
= 1.0
(62.4lb)(1.0)
= 62.4 lb/ft³
Volume of asphalt in binder:
8.82/62.4
= 0.14ft³
Specific weight of binder in mix:
2.65 x 62.4lb/ft³
= 165.36 lb/ft³
Volume of aggregate:
= 138.18/165.36
= 0.84ft³
Volume of void in the mix:
1ft³ - 0.84ft³ - 0.14ft³
= 0.02ft³
The percentage of void in total mix:
VTM = (0.02ft³/1ft³)100

Answer: Nuclear to thermal to mechanical to electrical.
Explanation:
Nuclear energy is also referred to as atomic energy which will then lead to the generation of the thermal energy. It should be noted that the thermal energy is also referred to as the heat energy and this is due to the rise in temperature which results in the faster movement of atoms and their collision with one another.
This in turn, brings about the mechanical energy which is simply the energy caused by the motion and this in turn, also lead to electrical energy.
Therefore, the correct answer is Nuclear to thermal to mechanical to electrical.
