Someone claims that in fully developed turbulent flow in a tube, the shear stress is a maximum at the tube surface. Is this clai
Alika [10]

Answer:

Yes this claim is correct.

Explanation:

The shear stress at any point is proportional to the velocity gradient at any that point. Since the fluid that is in contact with the pipe wall shall have zero velocity due to no flow boundary condition and if we move small distance away from the wall the velocity will have a non zero value thus a maximum gradient will exist at the surface of the pipe hence correspondingly the shear stresses will also be maximum.

What happens to the amperage draw of a condensing unit on a split AC system if the liquid line is restricted
cupoosta [38]

Answer:

The amperage draw of the condensing unit will be low.

Explanation:

A condensing unit is made up of a compressor and condenser, while an evaporating unit is made up of an evaporator coil.

A split AC system is a type of air conditioner system that has a condensing unit which is placed separately from the evaporative coil unit. Then the two units are connected to each other via a copper tube containing refrigerants.

The liquid line connects the condenser to the evaporator, and if this liquid line is restricted, the amp consumed by the condensing unit will be low.

ivanzaharov [21]

Answer:

"- Set the Orders object's sharing settings to Private in the Org-Wide Defaults

_Provide each partner with their own Salesforce login set to API Enabled on the profile

-Develop a custom Apex web service using the "With Sharing" keyword"

Explanation:

<em>Universal Containers (UC) has a requirement to expose a web service to their business partners. The web service will be used to allow each business partner to query UC's Salesforce instance to retrieve the status of orders. The business partner should only be allowed access to orders for which the business partner is the fulfillment vendor. The Architect does not want the business partners to utilize the standard APIs and would prefer a custom API be developed. Which three design elements should the Architect consider in order to ensure the data security of the solution?</em>

<em>A. Query the Orders object with Dynamic SOQL based upon the fulfillment ID. </em>

<em>B. Set the Orders object's sharing settings to Private in the Org-Wide Defaults </em>

<em>C. Provide each partner with their own Salesforce login set to API Enabled on the profile.  </em>

<em>D. Develop a custom Apex web service with a fulfillment ID input attribute </em>

<em>E. Develop a custom Apex web service using the "With Sharing" keyword.</em>

<em />

<em>The above should be a follow up option to the question</em>

The Architect should consider the following design

"- Set the Orders object's sharing settings to Private in the Org-Wide Defaults

_Provide each partner with their own Salesforce login set to API Enabled on the profile

-Develop a custom Apex web service using the "With Sharing" keyword"

 There is need for some sharing rule between the architect and the user
