Answer:

Differential analysis is used when it is needed to determine the detail information of the flow i.e. pressure or stress variation along any point.

Explanation:

In fluid mechanics, sometime situation arise in which we need to determine in detail about flow characteristics like stress and pressure variation.

To find these flow characteristics some relationship need to imply either at a point or at very small volume and analysis of flow at very small point is known as differential analysis.

Example: pressure and shear stress variation in a line of the wing of a plane.

1. It is known that there are some disadvantages in the casting of metal materials if the casting rate is high. Contrary to this

salantis [7]

Answer:

Some of the demerits or disadvantages of using a very slow castings rates in production of metal by the method of casting includes, with the solidification of metal, it may begin even before the mold is filled fully, which may result in defects such as shrinkage.

Secondly, the rate of slow casting will create castings that have a grain coarse structure that will affect the strength of the castings.

Explanation:

Solution

The disadvantageous of slow casting rates in the production of metals by casting method is explained below:

(1) The solidification of metal may start even before the mold is filled completely, which may create or produce defects such as mis-runs and shrinkage and shrinkage cavity.

So, the slow cavity rate will produce partial and incomplete castings

(2) Slow casting rate will produce castings which have a coarse grain structure which therefore affects the strength of the castings adversely.

A photovoltaic panel of dimension 2mÃ—4m is installed on the

blsea [12.9K]

Answer:

Explanation:

Simply put, a solar panel works by allowing photons, or particles of light, to knock electrons free from atoms, generating a flow of electricity. Solar panels actually comprise many, smaller units called photovoltaic cells. (Photovoltaic simply means they convert sunlight into electricity. The attached diagram give an ilustsration of the photovotaic pannel mounted on a roof top.

Solution

To Determine the electric power generated for

a) A still summer day.

E = A * r * H * PR

E = Total Amount of Energy in kilowatt

A = Total Surface Area

r = efficiency Rating

H = global radiation value

PR = Performance Ratio

kwh = watt * Time/1000

kwh = 100 * 35/1000

3.5

kwh = watt * Time/1000

kwh = 30 *15/1000

4.5

Blank is common during exercise.

Answer:

Sweat

Explanation:

As you exercise you respire and warm up due to energy. In turn, two things happen, blood vessels vasodilate (irrelevant to you) and sweat glands sweat more. this sweat then evaporates and cools down the body.

Compute the area and circumference of a circle given the radius r if the radius is greater than or equal to 1.0; otherwise, you

Maslowich

In this question we shall present the algorithm in pseudocode, whose structure is now summarized:

1) Inputs.

2) Algorithms.

3) Outputs.

Please notice that While-cycles consider the requirement of using the algorithm as many times as user wants.

Name: Area-or-Circunference

CHAR - decide

REAL - radius, circumference, area

Say "Do you want to calculate? [Y] - Yes/[N] - No";

Write decide;

While (decide != 'Y' and decide != 'y' and decide != 'N' and decide != 'n'):

Say "Invalid option. Do you want to calculate? [Y] - Yes/[N] - No";

Write decide;

end-While

While (decide = 'Y' or decide = 'y'):

Say "Please indicate a radius";

While (radius < 0):

Say "Radius must be equal or greater than 0. Please indicate a

radius";

Write radius;

end-While

If (radius < 1):

circumference = 2*3.14*radius;

Say "The circumference has a value of %circumference length units";

Else:

circumference = 2*3.14*radius;

area = 3.14*radius*radius;

Say "The circumference has a value of %circumference length units

and the area has a value of %area square units";

end-If

Say "Do you want to calculate? [Y] - Yes/[N] - No";

Write decide;

While (decide != 'Y' and decide != 'y' and decide != 'N' and decide !=

'n'):

Say "Invalid option. Do you want to calculate? [Y] - Yes/[N] - No";

Write decide;

end-While

If (decide = 'N' or decide = 'n'):

Say "Good luck";

end-If
