Iven & Find: Compare the average heat transfer coefficients for three different fluids. In all cases the length of the plate

is 1.6 m and the freestream velocity is 1 m/s moving parallel to the plate. Evaluate fluid properties at P = 1 atm and T = 300K. Each of the cases involves a different fluid
i) air,
ii) helium, and
iii) water. Fill in the table of properties for each of the fluids as you will need them in the calculations. Comment on the results.

Answer:

attached below

Explanation:

SO AS WE CAN SEE FOR GASES THE CONVECTIVE HEAT TRANSFER COEFFICIENT HAS VERY LOW VALUE WITH RESPECT TO LIQUID THATS WHY WE USE FIND TO MAXIMIZE HEAT TRANSFER RATE WITH GASES AS A CONVECTIVE MEDIUM.

Assume, X Company Limited (XCL) is one of the leading 4th generation Life Insurance
marishachu [46]

Answer:

The issues related to the privacy are:

1. Informational privacy

2. Discrimination factors

3. Biased grouping on the basis of Data mining

4. Lack of consent

5. Morally wrong

6. Illegal distribution of information risks

7. Possibility of threat to life

Let's look at some major concerns:

1. Informational privacy : The concept of privacy of the personal information is totally nullified when the information is being used for a purpose other than the intended one for which it was given. This unethical use of information even for general purposes is not correct and is a matter of concern. It is more like using the sensitive data of others for personal benefit which is purely objectionable and raises security issues. Sometimes the data is also shared with the potential employers which might have certain impacts we are unaware of.

2. Data mining issues : The process of using a certain information to arrive and understand the trend and outcomes is called data mining. In this case, the consumer's data undergoes grouping and might get placed in the wrong group rather than the actual one. Also, there can be a case of biasing towards the groups which are not be focused on, or are not a part of the intended audience. This leads to the discrimination factors if we see it from a social point of view.

3. Lack of consent : Use of information without the consent or awareness of the consumers raises concern over the business ethics followed by the company. No one deserves the right to misuse information for his personal benefits without any of its information to the consumer. It is morally wrong and againt the work ethics. Moreover, it raises trust issues between the two involved, and hence is socially unacceptable.

A metal wire of resistance R is cut into seven equal pieces that are then placed together side by side to form a new cable with
netineya [11]

Answer:

Explanation:

So therefore new Resistance R¹ = R/49

Resistance of a wire

R = ¶ * L/A

Where ¶ = resistivity of wire

L = length of wire

A = cross sectional area of wire

So therefore if the wire is cut into 7 equal lengths and joined together to form one with new Resistance R¹

So new length L¹ = 1L/7

New A¹ = 7A

So therefore R¹ = ¶ (L/7) /(7A)

So R¹ = ¶*L/A(49)

Since R = ¶L/A

So therefore R¹ = R/49

Answer:

In the clevis shown in Fig. 1-11b, find the minimum bolt diameter and the minimum thickness of each yoke that will support a load P = 14 kips without exceeding a shearing stress of 12 ksi and a bearing stress of 20 ksi.

127-fbd-clevis-double-shear-bolt.gifFor shearing of rivets (double shear)

P=τA

14=12[2(14πd2)]

d=0.8618in → diameter of bolt answer

For bearing of yoke:

P=σbAb

14=20[2(0.8618t)]

t=0.4061in → thickness of yoke answer

Which field in a Transmission Control Protocol (TCP) header is chosen from ephemeral ports?
zalisa [80]

Answer:

<u>Source Port</u>

Explanation:

When a connection is establish for an application, it assigns a port that is not in use as the source port. Such ports are known as ephemera ports, which are not related to specific protocol and are only allocated for the period of the connection. All data received on this port (until the connection is disconnected) is sent on to that application.
