The velocity distribution for laminar flow between parallel plates is given by u umax = 1 − ( 2y h ) 2 Where h is the distance s

eparating the plates and the origin is placed midway between the plates. Consider a flow of water at 150C, with umax = 0.10 m ∕ s and h = 0.1mm. Calculate the shear stress on the upper plate and give its direction. Sketch the variation of shear stress across the channel.

Answer:

Considering the plain view doctrine, which is an exception to the warrant requirement of the Fourth Amendment, is applied by law enforcement officers and courts who can seize evidence of a crime without a warrant, if the officer observes the evidence in plain view.

Explanation:

For any digital information related to a murder case that has been seized under the plain view doctrine to be used to convict you of a crime, has to comply with three conditions:

1. The digital evidence must be in out in the open, and easily observable by the officer, this is what "plain view" refers to.

2. The officer must have a legal right to be where he got the information related to the case.

3. The 'incriminating' character of the information must be a clear hint of the murder to fall under the plain view doctrine and the officer´s experience will help him determining whether the information is evidence or not, upon probable cause related to a crime.

Answer:

point B where $Q_B = 101.25 \ in^3$ has the largest Q value at section a–a

Explanation:

The missing diagram that is suppose to be attached to this question can be found in the attached file below.

So from the given information ;we are to determine the point that has the largest Q value at section a–a

In order to do that; we will work hand in hand with the image attached below.

From the image attached ; we will realize that there are 8 blocks aligned on top on another in the R.H.S of the image with the total of 12 in; meaning that each block contains 1.5 in each.

We also have block partitioned into different point segments . i,e A,B,C, D

For point A ;

Let Q be the moment of the Area A;

SO ; $Q_A = Area \times y_1$

where ;

$y_1 = (6 - \dfrac{1.5}{2})$

$y_1 = (6- 0.75)$

$y_1 = 5.25 \ in$

$Q_A =(L \times B) \times y_1$

$Q_A =(6 \times 1.5) \times 5.25$

$Q_A =47.25 \ in^3$

For point B ;

Let Q be the moment of the Area B;

SO ; $Q_B = Area \times y_2$

where ;

$y_2 = (6 - \dfrac{1.5 \times 3}{2})$

$y_2= (6 - \dfrac{4.5}{2}})$

$y_2 = (6 -2.25})$

$y_2 = 3.75 \ in$

$Q_B =(L \times B) \times y_1$

$Q_B=(6 \times 4.5) \times 3.75$

$Q_B = 101.25 \ in^3$

For point C ;

Let Q be the moment of the Area C;

SO ; $Q_C = Area \times y_3$

where ;

$y_3 = (6 - \dfrac{1.5 \times 2}{2})$

$y_3 = (6 - 1.5})$

$y_3= 4.5 \ in$

$Q_C =(L \times B) \times y_1$

$Q_C =(6 \times 3) \times 4.5$

$Q_C=81 \ in^3$

For point D ;

Let Q be the moment of the Area D;

SO ; $Q_D = Area \times y_4$

since there is no area about point D

Area = 0

$Q_D =0 \times y_4$

$Q_D = 0$

Thus; from the foregoing ; point B where $Q_B = 101.25 \ in^3$ has the largest Q value at section a–a
