A centrifugal pump having an impeller diameter of 1 m is to be constructed so that it will supply a head rise of 240 m at a flowrate of 4.2 m3/s of water when operating at a speed of 1200 rpm. To study the characteristics of this pump, a 1/5 scale, geometrically similar model operated at the same speed is to be tested in the laboratory. Determine (a) the required model discharge and (b) head rise. Assume that both model and prototype operate with the same efficiency (and therefore the same flow coefficient).

Propilot assist with navi-link's speed limit assist system works together to automatically adjust the vehicle's speed based on the posted speed limit and other traffic conditions.

When in auto mode, the system uses data from the navigation system to detect upcoming curves, exits, and interchanges, and adjusts the speed accordingly. Additionally, the speed limit assist system will provide an audible alert and display a visual warning on the instrument cluster if the vehicle exceeds the posted speed limit.

When the Speed Limit Assist system is engaged, the driver sets a desired speed, and the system will adjust the vehicle's speed to match the posted speed limit, up to the set speed. For example, if the driver sets the desired speed to 60 miles per hour and the posted speed limit is 55 miles per hour, the system will automatically adjust the vehicle's speed to 55 miles per hour.

The goal of Boeing, Inc is to determine whether an existing machine can mill an engine part that has a design specification of 5.0mm +- 0.10 mm. The process has a standard deviation of σ = 0.02 mm.

Given that the standard deviation of the process is σ = 0.02 mm. Now, we need to determine if the existing machine can produce a part that meets the design specification using the given standard deviation (σ).The tolerance limit (T.L) can be calculated as;

T.L = (Upper Limit – Lower Limit) / 2 where;

Upper Limit = 5.0 + 0.10 = 5.10 mm

Lower Limit = 5.0 – 0.10 = 4.90 mm

T.L = (5.10 – 4.90) / 2 = 0.10 / 2 = 0.05 mm

The value of T.L = 0.05 mm

The process standard deviation (σ) = 0.02 mm

Using the formula;

P = 0.6827, approximately 68.27% of the parts produced by the existing machine fall within the tolerance limit (5.0 ± 0.10)

With a process standard deviation of σ = 0.02 mm and a tolerance limit of 0.05 mm, approximately 68.27% of the parts produced by the existing machine fall within the tolerance limit (5.0 ± 0.10). It can, therefore, be concluded that the existing machine can produce parts that meet the design specification.

Answer:

From electrical energy to radiation

Explanation:

A light bulb converts electrical energy to light, which is nothing more than radiation. Don't regard radiation as a bad thing, this light is non-iodizing radiation, which does not have the possibility to alter our DNA, and thus it's safe.

The simplest example can be found in old lights (obsolete now because they are vastly inefficient). This lights were just resistors which turned electrical energy into heat. A very hot material reflects light in the form of radiation, as described above.

e. What would be the proper piece rate (rate expressed in money) for this job, assuming that the above time standard is correct?

Explanation:

Yes, if a refrigeration system is operating with two evaporators, one medium temperature and one low temperature, there should be a thermal expansion valve (TXV).

The TXV is necessary at the outlet of the low temperature evaporator because it helps to regulate the flow of refrigerant into the evaporator. The TXV also ensures that the refrigerant is properly metered and evaporated in the low temperature evaporator, which is essential for efficient operation of the refrigeration system.

On the other hand, the fixed orifice or capillary tube is installed at the outlet of the medium temperature evaporator to regulate the flow of refrigerant into the evaporator. This ensures that the refrigerant is properly metered and evaporated in the medium temperature evaporator, which is also essential for efficient operation of the refrigeration system.

Answer:

Shelf life.

Explanation:

In Business, an inventory is a term used to describe a list of finished goods, goods still in the production line and raw materials that would be used for the manufacturing of more goods in a bid to meet the unending consumer demands.

Simply stated, an inventory can be classified into three (3) main categories; finished goods, work in progress, and raw materials.

An inventory is recorded as a current asset on the balance sheet because it's primarily the most important source of revenue for a business entity.

Also, the three (3) main cost concept associated with an inventory are;

1. First In First Out (FIFO).

2. Last In First Out (LIFO).

3. Weighted average cost.

Shelf life can be defined as a measure of the length of time that a particular product could be kept or stored without it getting bad or becoming unsuitable for use by the consumers. Thus, the shelf life of a product is largely dependent on its expiration date.

Hence, merchandise without an expiration date like electronics, tools and home goods typically have a longer shelf life.

When the process is in control but does not meet specification, it is referred to as a special cause error.

In statistical process control, a process is considered to be in control when it operates within the defined limits and shows only random variations. However, when a process is in control but does not meet the desired specifications, it indicates the presence of a special cause error.

Special cause errors are attributed to specific factors or events that cause the process to deviate from the expected outcome. These errors are typically unpredictable and require investigation and corrective action to bring the process back within the desired specifications.

Student question: A 250KVA 11000 volts /50kHz single phase transformer has 80 turns on the secondary. Calculate: B) approximate number of primary turns C) the maximum value of the flux in 200 words

B) To find the approximate number of primary turns, we can use the transformer turns ratio formula:
Turns ratio = Primary turns / Secondary turns = Primary voltage / Secondary voltage

First, we need to calculate the secondary voltage. We can use the power formula:
Power = Voltage × Current
250 KVA = 11000 V × I
I = 250,000 VA / 11,000 V = 22.73 A

Now, we can find the secondary voltage:
Secondary voltage = Power / Current = 250,000 VA / 22.73 A = 11,000 V

Now, we can calculate the turns ratio:
Turns ratio = 11,000 V / 11,000 V = 1

Therefore, the approximate number of primary turns is:
Primary turns = Turns ratio × Secondary turns = 1 × 80 = 80 turns

C) To calculate the maximum value of the flux, we use the formula:
Flux = Voltage / (Frequency × Turns)

Since the frequency is given in kHz, we need to convert it to Hz:
50 kHz = 50,000 Hz

Now, we can find the maximum value of the flux:
Flux = 11,000 V / (50,000 Hz × 80 turns) = 0.00275 Wb

So, the maximum value of the flux in the transformer is approximately 0.00275 Weber (Wb).

Answer:

Hydrostatic force = 41168 N

Explanation:

Complete question

A triangular plate with a base 5 ft and altitude 3 ft is submerged vertically in water  so that the top is 4 ft below the surface. If the base is in the surface of water, find the force against onr side of the plate. Express the hydrostatic force against one side of the plate as an integral and evaluate it. (Recall that the weight density of water is 62.5 lb/ft3.)

Let "x" be the side length submerged in water.

Then

w(x)/base = (4+3-x)/altitude

w(x)/5 = (4+3-x)/3

w(x) = 5* (7-x)/3

Hydrostatic force = 62.5 integration of  x * 4 * (10-x)/3 with limits from 4 to 7

HF = integration of 40x - 4x^2/3

HF = 20x^2 - 4x^3/9 with limit 4 to 7

HF = (20*7^2 - 4*7^(3/9))- (20*4^2 - 4*4^(3/9))

HF = 658.69 N *62.5 = 41168 N

Compressional force/stress leads to the formation of Reverse fault type.What are faults?A fault is a crack or a fracture in the earth's crust in which rock formations can move past each other.

The friction and pressure between the plates generate compressional forces/stress, which compress or shorten the rock bodies until they crack or deform and create faults.When rock formations move past each other, this results in deformation. Compression forces lead to rocks shortening and thickening, which can lead to folds or faults in rock formations. On the other hand, tension forces lead to rock stretching, thinning, and forming normal faults. Shearing forces create strike-slip faults. Compressional forces generate reverse faults.Reverse faults occur when two rock formations move towards each other and compress each other, causing one rock body to slide upwards on another, resulting in a steeply inclined fault plane with the hanging wall moving upward relative to the footwall.

The thermal efficiency of the Brayton cycle in the cold air standard of 25° C is 45.60 %. The correct option is A.

A Brayton cycle is the thermodynamic cycle used in the heat engine. The process has been comprised of the events as:

The given conditions in the Brayton cycle are:

Inlet Temperature (T₁) = 25° C

Inlet pressure (P₁) = 95 kPa

Outlet pressure (P₂) = 1100 kPa

The efficiency of the cycle (η) can be calculated as:
