Answer:
Ventilation strategies fall into three general categories: Natural Dilution Ventilation (least effective) Mechanical Dilution Ventilation. Local Exhaust Ventilation (most effective)
Answer:
Electrical Capacitance
Explanation:
To find - unit of measure in SI for F
Solution -
The answer is - Electrical Capacitance
Reason -
The farad (symbol: F) is the SI derived unit of electrical capacitance, the ability of a body to store an electrical charge.

Capacitate electrică
Explicaţie:
Pentru a găsi - unitate de măsură în SI pentru F
Soluție -
Răspunsul este - Capacitate electrică
Motiv -
Farada (simbolul: F) este unitatea de capacitate electrică derivată din SI, capacitatea unui corp de a stoca o sarcină electrică.
Friction losses in pipes can be reduced by decreasing the length of the pipes, reducing the surface roughness of the pipes, and increasing the pipe diameter. Thus, options (c),(e), and (f) hold correct answers.
Friction loss is a measure of the amount of energy a piping system loses because flowing fluids meet resistance. As fluids flow through the pipes, they carry energy with them. Unfortunately, whenever there is resistance to the flow rate, it diverts fluids, and energy escapes. These opposing forces result in friction loss in pipes.
Friction loss in pipes can decrease the efficiency of the functions of pipes. These are a few ways by which friction loss in pipes can be reduced and the efficiency of the piping system can be boosted:
- <u><em>Decrease the length of the pipes</em></u>: By decreasing pipe lengths and avoiding the use of sharp turns, fittings, and tees, whenever possible result in a more natural path for fluids to flow.
- <u><em>Reduce the surface roughness of the pipes</em></u>: By reducing the interior surface roughness of pipes, a smooth and clearer path is provided for liquids to flow.
- <u><em>Increase the pipe diameter: </em></u>By widening the diameters of pipes, it is ensured that fluids squeeze through pipes easily.

Answer:
Applied Stress > 58.29 MPa
Explanation:
- Resolved shear stress should be greater than critically resolved shear stress in order to cause the single crystal to yield
Given angles are
∅ = 42.7 degree
Ф = 48.3 degree
Critically resolved shear stress = 28.5 MPa
If we consider
Critically resolved shear stress = resolved shear stress
Applied stress can be found by
(1)
Applied Stress =
Applied Stress =
Applied Stress = 58.29 MPa
We got reference
- By putting applied stress values of greater than 58.29 MPa in equation 1 we get
Resolved Shear Stress = 60 x Cos(48.3) x Cos(42.7)
Resolved Shear Stress = 29.33 MPa
Therefore, by the above calculation we conclude that applied stress should be greater than 58.29 MPa, In order to make resolved shear stress to be greater than critically resolved shear stress that is essential for single crystal to yield.
Answer:
evaluative criteria.
Explanation:
Evaluative criteria is a term in marketing that Is used when a customer decides to go for a different kind of product that is different from the one they originally had in mind because of certain attributes. These attributes could be objective in nature such as power and fuel economy or it could subjective when things like prestige and convenience are being looked at.
