Explanation:

On its current schedule, the plant can theoretically produce ...

  (30 pc/h/machine)(10 machine)(8 h/shift)(2 shift/day)(5 day/wk)(50 wk/yr)

  = (30)(10)(8)(2)(5)(50) pc/yr = 1,200,000 pc/yr

__

On the proposed schedule, this production becomes ...

  (30 pc/mach)(10 mach)(8 h/sh)(3 sh/da)(6 da/wk)(51 wk/yr)

  = (30)(10)(8)(3)(6)(51) pc/yr = 2,203,200 pc/yr

The increase in capacity is ...

  (2,203,200/1,200,000 -1) × 100% = 83.6% . . . capacity increase

_____

Additional comment

The number of parts per shift did not change. Only the number of shifts per year changed. It went up by a factor of (3/2)(6/5)(51/50) = 1.836. Hence the 83.6% increase in capacity.

We have to assume that maintenance and repair are done as effectvely as before in the reduced down time that each machine has.

polyethylene

Explanation:

The elasticity of polyethylene makes it an ideal material for food packaging. Polyethylene is used extensively in the automotive industry. Polyethylene is often used for manufacturing stock poly bags, zip lock bags, bottles, food containers, food crates, stretch film, tape, pallets and plastic sheeting.

Polythene is commonly used as a packaging material. The most common polyethylene types used in food packaging are high-density polyethylene (HDPE), low-density polyethylene (LDPE), and linear low-density polyethylene (LLDPE).

One of the most popular materials used in the food industry for packaging is petroleum plastics (synthetic polymers). Such polymers include polyethylene terephthalate (PET), low and high-density polyethylene (LDPE and HDPE respectively), polypropylene (PP), polyvinyl chloride (PVC), and polystyrene (PS). Paper, paperboard, and cardboard cartons are frequently used as packaging for products in stores as well as used in shipping. Corrugated cardboard, for example, has excellent structural stability for shipping, storing, and even marketing products.

A) Sewage Factor: It represents the proportion of water inflow that is expected to be discharged as sewage. It is used in the design of sewer systems to estimate the quantity of sewage flow that will be generated.

B) Connection Factor: It represents the percentage of buildings or properties that are expected to connect to a sewer system. It is used in the design of sewer systems to estimate the total number of connections that will be made to the system.

C) Infiltration Coefficient: It represents the rate at which water enters a sewer system through cracks, joints, and other defects in pipes. It is used in the design of sewer systems to estimate the volume of infiltration that will occur during wet weather conditions.

D) Design Period: It is the length of time for which a particular engineering project is designed to function effectively. For example, in the case of water supply systems, the design period may be 20-30 years, during which the system is expected to meet the water demand requirements of the users.

E) Drop Manhole: It is a type of manhole that is constructed at a location where the sewer pipe changes direction from a horizontal to a vertical alignment. The purpose of a drop manhole is to reduce the velocity of the sewage flow and prevent damage to the downstream sewer structures.

F) Self Cleansing Velocity: It is the minimum velocity required in a sewer pipe to prevent the deposition of solids and ensure the self-cleansing of the pipe. A value of twice the average velocity is commonly used as the self-cleansing velocity.

The factors that affect water demand include population size, economic activity, climate, lifestyle, and water pricing policies. Changes in any of these factors can influence the level of water demand in a given area. For example, an increase in population size or economic activity can lead to a higher demand for water, while the implementation of water conservation measures can reduce water demand.

When attempting to free a vehicle stuck in snow, it is recommended to shift into a low gear, such as 1st or 2nd gear.

This provides more torque to the wheels, allowing them to gain more traction and power through the snow. Neutral should not be used as it disengages the transmission from the wheels, making it impossible to move the vehicle forward or backward. Reverse gear may be useful in some situations, but it should be used with caution as it can cause the snow to build up in front of the tires, making it even more difficult to free the vehicle. It is also important to use gentle acceleration and avoid spinning the wheels excessively, as this can cause further snow buildup and make it even more challenging to free the vehicle. Additionally, it is always a good idea to have a shovel, sand or kitty litter, and tire chains on hand when driving in snowy conditions to help prevent getting stuck in the first place.

The bar assembly is missing, so i have attached it.

Answer:

Minimum required dimensions are; h1 = 2 inches and h2 = 4 inches

Explanation:

We are given;

Yield stress; σY = 45 ksi

Factor of safety; F.S = 1.5

Applying conditions of Equilibrium Σx = 0 and Σy = 0,

At segment AB in the diagram with Σx = 0 , we have;

-30 + N_ab = 0

N_ab = 30 kip

The cross sectional area of AB will be;

A_ab = (h1 × 0.5) in²

Now, since we have a factor of safety as 1.5,our allowable normal yield stress will be calculated from;

σ_allow = σY/F.S

So, σ_allow = 45/1.5

σ_allow = 30 ksi

Now, normal allowable yield stress is also calculated as;

σ_allow = N_ab/A_ab

So plugging in the relevant values, we can find h1.

So,

30 = 30/0.5h1

h1 = 30/(30 × 0.5)

h1 = 2 inches

Similarly, we can do the same for BC.

The cross sectional area of BC will be;

A_bc = (h2 × 0.5) in²

At segment BC in the diagram with Σx = 0 , we have;

-30 - 15 - 15 + N_bc = 0

N_bc = 60 kip

σ_allow = N_bc/A_bc

So,

30 = 60/0.5h2

h2 = 60/(0.5 × 30)

h2 = 4 inches

Minimum required dimensions are; h1 = 2 inches and h2 = 4 inches

Engineers desire to keep objects like bridges in the "safe" zone.

This refers to the area in which the bridge can withstand various external forces, such as wind, rain, and weight, without collapsing or becoming unsafe for use.  Bridges are critical components of infrastructure that allow people to travel safely and efficiently over bodies of water or other obstacles. They are often subjected to harsh environmental conditions, such as high winds, earthquakes, and heavy precipitation, which can cause significant damage if the bridge is not designed and maintained properly.

Therefore, engineers strive to ensure that bridges remain within the safe zone, which is determined by various factors such as the materials used, the design of the bridge, and the loads that it is expected to carry. The safe zone is established based on calculations that take into account the various forces that a bridge may encounter during its lifetime. This includes not only the weight of vehicles passing over the bridge but also other factors such as the impact of wind, the effects of temperature changes, and the effects of water and other environmental factors.

Overall, the safe zone is critical to ensuring the safety of individuals who use bridges regularly. Engineers work diligently to design and maintain bridges to keep them within the safe zone, which ensures that they can withstand the forces they are subjected to over time, without endangering the lives of the people who rely on them.

Answer:

When a system is produced using the evolutionary development model, features tend to be added without regard to an overriding design. With each modification, the software becomes increasingly disorganized. System maintenance hampered by these problems, as it is harder identifying the source of bugs in poorly designed systems. Also, keeping the documentation up to date over successive "evolution" is uncommon. Poor documentation also makes maintenance more difficult.

Explanation:

・It leads to implementing and then repairing way of building systems.

・Practically, this methodology may increase the complexity of the system as scope of the system may expand beyond original plans.

・Incomplete application may cause application not to be used as the full system was designed.

・Their results have incomplete or inadequate problem analysis.

An "anticlinal" trap is one of the most effective structures for forming a petroleum reservoir. An impermeable layer of rock forms a cap over a layer of porous permeable sedimentary rock in this location. If petroleum is present, it drifts upward and becomes trapped within the anticline fold.

What is a anticlinal trap structure?

An anticline is the structural-trap formed by the rock strata folding into an arch-like shape. The rock layers in an anticlinal trap were originally laid down horizontally before folding into an arch-like shape known as an anticline due to earth movement.

This type of structure can be seen on a seismic section, but because seismic sections are typically 'time sections,' the actual structure can be obscured by velocity changes above the anticline. The structural contours of an anticline form closed loops.

To determine the height in the water at a radius of 10 cm, we must first calculate the volume of the cylinder.

The volume of a cylinder is equal to the product of its height and the area of its base. The area of the base of the cylinder is equal to πr2, where r is the radius. The radius of the cylinder is equal to the diameter divided by two, which is 20 cm. Thus, the area of the base is equal to π(20 cm)2, or 1256.64 cm2. The volume of the cylinder is then equal to 1256.64 cm2 x 90 cm, or 113707.6 cm3.  

Since the cylinder is partially filled with 60 cm of water, the volume of water in the cylinder is equal to 1256.64 cm2 x 60 cm, or 75398.4 cm3. The height in the water at a radius of 10 cm is then equal to (75398.4 cm3 / 1256.64 cm2) x 10 cm, or 596.84 cm. Therefore, the height in the water at a radius of 10 cm is 596.84 cm.

What is pressure?
By pressing a knife against some fruit, one can see a straightforward illustration of pressure. The surface won't be cut if you press the flat part of the knife against the fruit. The force is dispersed over a wide area (low pressure).

a)Mass flow rate of the refrigerant
Therefore h1= condenser inlet enthalpy =278.28KJ/Kg
saturation temperature at 1.2mpa is 46.29C
Therefore the temperature of the condenser

T2 = 46.29C - 5
T2 = 41.29C

Now,
d)power consumed by compressor W = 3.3KW
Q4 = QL + w = Q4
QL = mR(h1-h2)-W
= 0.0498 x (278.26 - 110.19)-3.3
=5.074KW
Hence refrigerator load is 5.74Kg

(COP)r = 238/53
(Cop) = 4.490

Therefore the above values are the (a) mass flow rate of the refrigerant, b) the refrigerant load, c) the cop, and d) the minimum power input to the compressor for the same refrigeration load.
