Answer:

Answer:

1)ΔL = 0.616 mm

2)Δd = 0.00194 mm

Explanation:

We are given;

Force; F = 52900 N

Initial length; L_o = 207 mm = 0.207 m

Diameter; d_o = 19.2 mm = 0.0192 m

Elastic modulus; E = 61.4 GPa = 61.4 × 10^(9) N/m²

Now, from Hooke's law;

E = σ/ε

Where; σ is stress = force/area = F/A

A = πd²/4 = π × 0.0192²/4

A = 0.00009216π

σ = 52900/0.00009216π

ε = ΔL/L_o

ε = ΔL/0.207

Thus,from E = σ/ε, we have;

61.4 × 10^(9) = (52900/0.00009216π) ÷ (ΔL/0.207)

Making ΔL the subject, we have;

ΔL = (52900 × 0.207)/(61.4 × 10^(9) × 0.00009216π)

ΔL = 0.616 × 10^(-3) m

ΔL = 0.616 mm

B) Poisson's ratio is given as;

υ = ε_x/ε_z

ε_x = Δd/d_o

ε_z = ΔL/L_o

Thus;

υ = (Δd/d_o) ÷ (ΔL/L_o)

Making Δd the subject gives;

Δd = (υ × d_o × ΔL)/L_o

We are given Poisson's ratio to be 0.34.

Thus;

Δd = (0.34 × 19.2 × 0.616)/207

Δd = 0.00194 mm

Answer:

The most accurate reading for an analog meter is a pointer position between 2/3 of full scale and full scale. Typically, dc voltage measurements use the full count capability of the ADC, since signal conditioning is rather straight forward: it uses resistive dividers and filters.

H is the enthalpy of the gas, Hf is the enthalpy of the fuel, m is the mass flow rate of air, Vexit and Vinlet are the exit and inlet velocities.

Mass is the measure of the amount of matter an object contains. It is measured in kilograms (kg) in the International System of Units (SI). Mass is also known as a measure of inertia, which is the resistance of an object to change its velocity or its direction. In other words, mass is the measure of an object's resistance to acceleration.

The specific thrust is the amount of thrust generated per unit mass flow rate of air through the engine. It can be calculated by the following equation:

T = m * (Vexit – Vinlet)

where m is the mass flow rate of air and Vexit and Vinlet are the exit and inlet velocities respectively.

TSFC

The TSFC is the amount of fuel consumed per unit of thrust produced. It can be calculated by the following equation:

TSFC = (mf/T) * (Vexit – Vinlet)

where mf is the fuel flow rate and T is the thrust generated.

T04

T04 is the temperature of the gases exiting the combustor. It can be calculated from the energy equation, which is given by:

H = Hf + m * (Vexit2/2 – Vinlet2/2) + mf * (Qf – Hf)

An automatic stabilizer is an economic policy instrument that automatically adjusts to counteract fluctuations in economic activity without any deliberate intervention by policymakers.

They are designed to stabilize an economy by decreasing the impact of economic shocks, such as recessions or booms, and help maintain a consistent level of economic growth.

A prime example of an automatic stabilizer is the progressive income tax system. In this system, as an individual's income increases, they are subjected to higher tax rates. Conversely, as their income decreases, they pay lower tax rates. During economic expansions, when individuals' incomes rise, the government collects more taxes, which helps reduce inflationary pressures. Conversely, during recessions, when incomes fall, the government collects fewer taxes, providing an automatic boost to disposable income and, in turn, consumer spending.

Another illustration of an automatic stabilizer is unemployment benefits. When the economy experiences a downturn and unemployment rates increase, the government automatically provides financial assistance to those who have lost their jobs. This support not only helps the unemployed meet their basic needs but also sustains consumer spending, which in turn helps stabilize the economy.

In summary, automatic stabilizers, such as the progressive income tax system and unemployment benefits, play a crucial role in mitigating economic fluctuations. They work passively without the need for active policy intervention, providing a stabilizing effect that helps maintain economic growth and reduces the severity of economic shocks.

Answer:

It is economical

Explanation:

Given data for determining

cost of product = £5 per kg

cost of solvent = £20 per /kg

additional solvent makeup = 10 kg/d

current loss of product = 0.7 kg/h

anticipated recovery of product = 80%

additional service ( utility cost ) = negligible

Determine if it is economical to install the recovery system

cost of product = £5 per kg

cost of solvent = £20 per /kg

additional solvent required = 10 kg / d

cost of additional solvent in a day  = £200 / day  ( £20 per kg * 10 kg / d )

product lost = 0.7 kg/h

product recovered = 0.7 * 80% = 0.56 kg/h

therefore product recovered in a day = 0.56 * 24 = 13.44 kg / day

Next :

calculate income generated from product recovery

13.44 kg/day *  £20 /kg =  £268.88 / day

Determine if it is economical

Income - cost

= £268.88 - £200

=  £68.88  ( hence it is economical )

Solution :

The treatment system will operate as the well mixed chamber.

Disinfection rate constant for the UV light, k is 7.80 /s. Number of bacteria in water need to be reduced by 99.9%

Percent reduction of bacteria should be \($(1-10^{0.99}) \times 100 =89.7\%$\)

Volume of the unit chamber is fixed at 2L

Assume the inlet concentration, \($C_0$\) as 1000

The outlet concentration of bacteria, C should be \($1000-\left(1000 \times \frac{89.7}{100}\right)$\)

                                                                                  = 103

The well mixed chamber will then follow a completely mixed flow reactor model.

Compute the time required :

\($t=\frac{1}{k}\left(\frac{C_0}{C}-1\right)$\)

\($t=\frac{1}{7.8}\left(\frac{1000}{103}-1\right)$\)

  = 1.115 s

Flow through the system is    \($\frac{2 \ L}{1.115 \ s}$\)  = 1.79 L/s

The amount of water treated during the 10 hours of sunlight is 1.79 x 10 x 60 x 60 = 64440 L

Irregular Task Think about the cruise control system in a car. The main purpose of cruise control is to maintain a consistent speed for the vehicle. Let's say the driver has set the target speed at 60 mph.

The inbuilt computer sends a signal to the engine controller to set the speed appropriately if the vehicle is moving slower or faster than the selected speed. Control rate, which is established by the designer of the control system, is the frequency at which the computer checks to see if the vehicle's current speed is consistent with the programmed speed.

In summary, the XYZ Company will require:

(a) 705 processing and assembly operations,

(b) 710 workers (direct labor only), and

(c) 25,738 m2 of total floor space for the new plant.

To calculate the required processing and assembly operations, workers, and total floor space for the new factory, we can break down the problem into smaller parts and analyze each element.

(a) Processing and assembly operations:

Number of components made in the factory: 250 components * 35% = 87.5 (round up to 88 components)

Processing operations for components: 88 components * 8 processing operations = 704 processing operations

Assembly operations for final product: 1 assembly operation (as each product is assembled in one workstation)

Total operations = 704 processing operations + 1 assembly operation = 705 operations

(b) Number of workers (direct labor only):

Processing workers: 704 processing operations / 1 (one worker per work cell) = 704 workers

Assembly workers: 13 models * 1000 units/model = 13,000 units/year

Assembly time per unit: 48 min/unit = 0.8 hr/unit

Assembly time for all products: 13,000 units * 0.8 hr/unit = 10,400 hr

Assembly workers required: 10,400 hr / 2,000 hr/shift = 5.2 (round up to 6 workers)

Total workers = 704 processing workers + 6 assembly workers = 710 workers

(c) Total floor space required:

Processing floor space: 704 work cells * 25 m2/cell = 17,600 m2

Assembly floor space: 6 workstations * 25 m2/station = 150 m2

Total production area: 17,600 m2 + 150 m2 = 17,750 m2

Additional allowance (45%): 17,750 m2 * 45% = 7,987.5 m2

Total floor space = 17,750 m2 + 7,987.5 m2 = 25,737.5 m2 (round to 25,738 m2)

In summary, the XYZ Company will require:

(a) 705 processing and assembly operations,

(b) 710 workers (direct labor only), and

So the bouy does not float with its axis vertical

Explanation:

From the question we are told that:

Diameter \(d=2m\)

Length \(l=2.5m\)

Weight \(W=22kN\)

Specific weight of sea water \(\mu= 10.25kN/m^3\)

Generally the equation for weight of cylinder is mathematically given by

Weight of cylinder = buoyancy Force

\(W=(pwg)Vd\)

Where

\(V_d=\pi/4(d)^2y\)

Therefore

\(22*10^3=10.25*10^3 *\pi/4(2)^2y\\\\\22*10^3=32201.3247y\\\\\y=1.5m\)

Therefore

Center of Bouyance B

\(B=\frac{y}{2}=0.26m\\\\B=0.75\)

Center of Gravity

\(G=\frac{I.B}{2}=2.6m\)

Generally the equation for\BM is mathematically given by

\(BM=\frac{I}{vd}\\\\BM=\frac{3.142/64*2^4}{3.142/4*2^2*0.5215}\\\\BM=0.479m\\\\\)

Therefore

\(BG=2.6-0.476\\\\BG=0.64m\)

Therefore

\(GM=BM-BG\\\\GM=0.479m-0.64m\\\\GM=-0.161m\\\\\)

Therefore

\(GM<0\)
