Answer:

Pulser switch :-

Advertisements. A Switch is a device that makes or breaks a circuit or a contact. As well, it can convert an analog data into digital data.

Data switch :-

A switch box that routes an input signal to an output line; for example, to connect two computers to one printer. Manual data switches have dials or buttons. Automatic switches test for signals on the input lines and provide first-come, first-served switching.

In a 1D compression test with double drainage, the pore pressure readings are practically zero after 8 minutes for a clay sample

frosja888 [35]

Answer:

The duration of the consolidation process for the same clay is 32 min

Explanation:

for clay 1:

t1=0

H1=thickness=2 cm

for the clay 2:

t2=?

H2=2 cm

The time factor is equal to:

$T=(\frac{Cv}{d^{2} })t$

where Cv is the coefficient of consolidation

$(\frac{Cvt}{d^{2} })_{1}= (\frac{Cvt}{d^{2} })_{2}$

if Cv is constant, we have:

$(\frac{t1}{(\frac{H1}{2}) ^{2} })_{1}=(\frac{t2}{H2^{2} })_{2}\\\frac{0}{(\frac{2}{2})^{2}) }=\frac{t2}{2^{2} }$

Clearing t2:

t2=32 min

Your company is planning to build a pipeline to transport gasoline from the refinery to a field of storage tanks. The parameters

AleksandrR [38]

Answer:

The model system will need water flowing at a velocity of 2.07 meters per second to guarantee kinematic similarity in the form of equal Reynolds numbers.

Explanation:

The Reynolds number ( $Re_{D}$ ) is a dimensionless criterion use for flow regime of fluids, which is defined as:

$Re_{D} = \frac{\rho \cdot v\cdot D}{\mu}$ (Eq. 1)

Where:

$\rho$ - Density, measured in kilograms per cubic meter.

$\mu$ - Dynamic viscosity, measured in kilograms per meter-second.

$v$ - Average flow velocity, measured in meters per second.

$D$ - Pipe diameter, measured in meters.

We need to find the equivalent velocity of water used in the prototype system. In this case, we assume that $Re_{D,gas} = Re_{D,w}$ . That is:

$\frac{\rho_{w}\cdot v_{w}\cdot D_{w}}{\mu_{w}} = \frac{\rho_{gas}\cdot v_{gas}\cdot D_{gas}}{\mu_{gas}}$ (Eq. 2)

Where subindex $w$ is used for water and $gas$ for gasoline.

If we know that $\rho_{gas} = 690\,\frac{kg}{m^{2}}$ , $\mu_{gas} = 0.006\,\frac{kg}{m\cdot s}$ , $v_{gas} = 0.5\,\frac{m}{s}$ , $D_{gas} = 1\,m$ , $\rho_{w} = 1000\,\frac{kg}{m^{3}}$ , $\mu_{w} = 0.0018\,\frac{kg}{m\cdot s}$ and $D_{w} = 0.05\,m$ , then we get the following formula:

$57500 = 27777.778\cdot v_{w}$

The fluid velocity for the prototype system is:

$v_{w} = 2.07\,\frac{m}{y}$

The model system will need water flowing at a velocity of 2.07 meters per second to guarantee kinematic similarity in the form of equal Reynolds numbers.

Natali [406]

Answer:

Sarah is asking each department head how long they can be without their primary system. Sarah is trying to determine the Recovery Time Objective (RTO) as this is the duration of time within which the primary system must be restored after the disruption.

Recovery Point Objective is basically to determine the age of restoration or recovery point.

Business recovery and technical recovery requirements are to assess the requirements to recover by Business or technically.

Hence, Recovery Time Objective (RTO) is the correct answer.

The 2-kg package leaves the conveyor belt at with a speed of vA = 1 m/s and slides down the smooth ramp. Determine the required

Kisachek [45]

Answer:

Incomplete question: Find the normal reaction the curved portion of the ramp exerts on the package at B if pB = 2 m, the height is 4 m

Answer: The required speed is 8.9107 m/s

The normal reaction is 99.0006 N

Explanation:

Given data:

m = 2 kg

vA = speed = 1 m/s

h = 4 m

g = gravity = 9.8 m/s²

Questions: Determine the required speed of the conveyor, vc = ?

Find the normal reaction, Nc = ?

The required speed applying the conservation of energy:

$\frac{1}{2} mv_{A}^{2} +mgh=\frac{1}{2} mv_{c} ^{2}$

Solving for vc:

$v_{c} =\sqrt{v_{A}^{2}+2gh } =\sqrt{1^{2}+(2*9.8*4) } =8.9107m/s$

The normal reaction applying the equilibrium of forces:

$N_{c} -mg=m(\frac{v_{c}^{2} }{p_{B} } )$

$N_{c} =2*(\frac{8.9107^{2} }{2} )+(2*9.8)=99.0006N$
