For those who run or work in a business that handles food, you understand the importance of food safety and regulation compliance as it pertains to not only to certification and licensing of a company, but also the life or death of those who consume the products. Because food safety is such an important issue, we want to ensure that all companies who work in the production, preparation, or processing of food have the tools and information they need to ensure they are in full compliance 100% of the time. One slip in food safety compliance could cost someone their health or life, and this information spreads mistrust in the general public toward the company who sold the product, and also the entire product across companies throughout an entire country and beyond. So how does each company working with food ensure they comply with each and every food safety regulation? Through excellent auditing tools.

Auditing in Food Safety Must Change

Auditing in food safety compliance is essential in ensuring that all regulations are being complied with. Most auditing practices for major companies are severely out of date. Many rely on several different forms, stacks of paperwork, and data stored on multiple different computers and databases. This is incredibly inefficient, as it can be easy to miss something when comparing one sheet to the next, and paper can easily be lost or destroyed. It is also time consuming for companies to share audits over separate computers and databases, as it must be passed down from one employee to the next. Technology has granted all food safety compliance managers a simple solution. Auditing apps are the new wave solutions for companies who want all of their data stored on one cloud database that is instantly accessible with real-time data for all employees. This means that no one ever gets left out of the loop, and no new information will fall through the cracks.

Answer:

<E1, E2>.

Explanation:

So, in the question above we are given that the Two Electric field vectors E1 and E2 are perpendicular to each other. Thus, we are going to have the i and the j components for the two Electric Field that is E1 and E2 respectively. That is to say the addition we give us a resultant E which is an arbitrary vector;

E = |E| cos θi + |E| sin θj. -------------------(1).

Therefore, if we make use of the components division rule we will have something like what we have below;

x = |E2|/ |E| cos θ and y = |E1|/|E| sin θ

​

Therefore, we will now have;

E = x |E2| i + y |E1| j.

The base vectors is then Given as <E1, E2>.

Here are the steps to replace old weather stripping on a door:

Remove the Old Weather Stripping To remove the old weather stripping, use a putty knife to loosen the adhesive or nails that hold the stripping in place. Once the weather stripping is loose, you can remove it by pulling it off the door.

Clean the Door Surface After removing the old weather stripping, clean the door surface thoroughly. This will ensure that the new weather stripping adheres properly. Use a clean, dry cloth to wipe the surface clean.

Measure and Cut the New Weather Stripping Measure the length of the door jamb and cut the new weather stripping to fit. Be sure to leave a small amount of excess weather stripping so that it overlaps at the ends.

Install the New Weather Stripping Once you have cut the new weather stripping, peel off the backing to expose the adhesive. Carefully place the weather stripping onto the door jamb, starting at the top and working your way down. Be sure to press the weather stripping firmly against the door jamb to ensure a secure fit.

Check the Fit Test the fit of the new weather stripping by closing the door. The weather stripping should form a tight seal around the door. If there are any gaps or spaces, adjust the weather stripping as needed.

In this scenario, a pipeline made of carbon steel failed after three years of operation due to corrosion. The wall thickness of the pipeline had reduced to about half of its original value. The pipeline was constructed of nominal 100 mm (4 in) schedule 40 pipe, with an inside diameter of 102.3 mm (4.026 in) and an outside diameter of 114.3 mm (4.5 in).

To estimate the rate of corrosion in IPY (inches per year) and mm per year, we need to use the following formula:

Rate of Corrosion = (Original Thickness - Remaining Thickness) / (Operation Time x Corrosion Allowance)

The original thickness of the pipeline can be calculated as:

Original Thickness = (Outside Diameter - 2 x Corrosion Allowance)

We know that the outside diameter of the pipeline is 114.3 mm (4.5 in) and the schedule 40 pipe has a corrosion allowance of 3.05 mm (0.12 in). Therefore, the original thickness can be calculated as:

Original Thickness = (114.3 mm - 2 x 3.05 mm) = 108.2 mm (4.26 in)

Now we can use the formula to estimate the rate of corrosion in IPY and mm per year:

Rate of Corrosion in IPY = (Original Thickness - Remaining Thickness) / (Operation Time x Corrosion Allowance)
Rate of Corrosion in IPY = (108.2 mm - 0.5 x 108.2 mm) / (3 years x 0.12 in)
Rate of Corrosion in IPY = 49.6 IPY

Rate of Corrosion in mm per year = (Original Thickness - Remaining Thickness) / (Operation Time x Corrosion Allowance)
Rate of Corrosion in mm per year = (108.2 mm - 0.5 x 108.2 mm) / (3 years x 3.05 mm)
Rate of Corrosion in mm per year = 4.8 mm/year

The rate of corrosion in IPY is estimated to be 49.6 IPY, and in mm per year, it is estimated to be 4.8 mm/year. These calculations help us to understand the rate at which the pipeline deteriorated due to corrosion, which can be used to prevent future failures and ensure the safety and longevity of similar pipelines.

On the orifice with a 50 mm in diameter opening:

(a) The volume flow rate of water through the pipe is:

\(Q = A_v v\)

where A_v = area of the orifice and v = velocity of the flow.

The area of the orifice is:

\(A_v = \pi ( \frac{d}{2} )^2 = \pi (\frac{50}{2})^2 = 1962.5 mm^2\)

The velocity of the flow is:

\(v = \sqrt{2gH} = \sqrt{2(9.81)(0.15)} = 1.715 m/s\)

Therefore, the volume flow rate is:

Q = 1962.5 mm² × 1.715 m/s = 3.375 m³/s

(b) The average velocity of the flow is:

\(v_avg = Q/A_p = Q/(\pi (\frac{d}{2})^2) = 3.375 m^3/s / (\pi (\frac{100}{2})^2) = 1.082 m/s\)

(c) The head loss caused by the orifice meter is:

\(H_L = \frac{v^2}{2g} = \frac{(1.715)^2}{2(9.81)} = 0.15 m\)

(d) The height of water column required if replaced with water manometer is:

\(H_w = \frac{\rho_m}{\rho_w} H_m = \frac{13.6}{1} (0.15) = 2.04 m\)

Therefore, the answers to your questions are:

(a) The volume flow rate of water through the pipe is 3.375 m^3/s.

(b) The average velocity of the flow is 1.082 m/s.

(c) The head loss caused by the orifice meter is 0.15 m.

(d) The height of water column required if replaced with water manometer is 2.04 m.

Sum of forces is zero and there is no resultant force .

Minimum cross sectional area can not be determined with the available information.

Given,

Vertical load = 10 kN

Modulus of elasticity = 200GPa

Yield stress on the cable = 400 MPa

Safety factor = 2.0

Now,

Let

L = \(\sqrt{(1.5)^{2} + (1.5)^2 }\)

L = 3.35 m

substituting 1.5 m for h and 1.5 m for the term (a + b)

Ф = tan⁻¹(1.5/1.5)

Ф = 45⁰

Substituting 1 for h and 3 m for (a+ b) yields:

Ф = tan⁻¹(1/3)

Ф = 25.56⁰

Since the sum of the forces is zero, the system is balanced and there is no resultant force.

In Stokes flow, the fluid velocity is proportional to the forces acting on the fluid and the fluid is assumed to be viscous and incompressible. The fluid velocity near a rotating sphere in Stokes flow can be determined using the equations of fluid dynamics.

Kinematic reversibility is a property of Stokes flow, which states that the fluid flow is symmetric with respect to time reversal. This means that if the fluid velocity is recorded at a certain time, then the same velocity field will be obtained if time is reversed and the flow is replayed in the reverse direction.

When a sphere is rotating near a wall, the flow of fluid around the sphere creates a velocity field that pushes the sphere away from the wall. This flow can be considered as the fluid being pushed away from the sphere and towards the wall. If the flow is time-reversed, the fluid velocity field would be the same, but the direction of the velocity would be reversed. This means that the fluid would be drawn towards the sphere and away from the wall, pulling the sphere towards the wall.

Therefore, based on the property of kinematic reversibility in Stokes flow, the rotating sphere near a wall will experience a force that could either push it away from the wall or draw it towards the wall, depending on the direction of the flow.

Explanation:

3 broken wires in one strand in one lay are cause for removal from service.

Answer:

Answer:

Used to recall the direction a standard screw

Answer:

A) Power output = 541.67 MW

B) Backwork ratio = 0.4

C) Improved thermal efficiency = 0.598

Explanation:

We are given;

Net power output; W'_net = 325 MW

Minimum Temperature; T1 = 300 K

Maximum Temperature; T4 = 1500 K

Compression Pressure ratio;P2/P1 = 12

From online tables, we have the following properties of air;

Specific heat capacity; C_p = 1.004 KJ/Kg

Adiabatic constant; k = 1.4

Temperature at stage 2 will be given by the formula;

T2 = T1(P2/P1)^((k - 1)/k)

Plugging in the relevant values gives;

T2 = 300(12)^((1.4 - 1)/1.4)

T2 = 610.18 K

Similarly, Temperature at stage 3 will be;

T3 = T4(P2/P1)^((k - 1)/k)

Plugging in the relevant values gives;

T3 = 750(12)^((1.4 - 1)/1.4)

T3 = 1525.45 K

Now, let's calculate the specific heat addition given by the formula;

q = C_p(T3 - T2)

q = 1.004(1525.45 - 610.18)

q = 918.93 KJ/Kg

Let's now calculate the specific net work output;

w_net = C_p[(T3 - T4) - (T2 - T1)]

w_net = 1.004[(1525.45 - 750) - (610.18 - 300)]

w_net = 467.13 KJ/Kg

A) Power output is given by;

W_T = (W'_net/W_net) × C_p(T3 - T4)

W_T = (325/467.13) × 1.004(1525.45 - 750)

W_T = 541.67 MW

B) back work ratio is;

f = (T2 - T1)/(T3 - T4)

f = (610.18 - 300)/(1525.45 - 750)

f = 0.4

C) Thermal efficiency is given by;

η = w_net/q

Since we are told that a regenerator, with an effectiveness of 85 percent, were installed in the power plant.

Thus;

η = (w_net/q)÷0.85

η = (467.13/918.94) ÷ 0.85

η = 0.598
