Use phasor techniques to determine the impedance seen by the source given that R = 4 Ω, C = 12 μF, L = 6 mH and ω = 2000 rad/sec
Zielflug [23.3K]

Answer:

Z = 29.938Ω ∠22.04°

I = 2.494A

Explanation:

Impedance Z is defined as the total opposition to the flow of current in an AC circuit. In an R-L-C AC circuit, Impedance is expressed as shown:

Z² = R²+(Xl-Xc)²

Z = √R²+(Xl-Xc)²

R is the resistance = 4Ω

Xl is the inductive reactance = ωL

Xc is the capacitive reactance =

1/ωc

Given C = 12 μF, L = 6 mH and ω = 2000 rad/sec

Xl = 2000×6×10^-3

Xl = 12Ω

Xc = 1/2000×12×10^-6

Xc = 1/24000×10^-6

Xc = 1/0.024

Xc = 41.67Ω

Z = √4²+(12-41.67)²

Z = √16+880.31

Z = √896.31

Z = 29.938Ω (to 3dp)

θ = tan^-1(Xl-Xc)/R

θ = tan^-1(12-41.67)/12

θ = tan^-1(-29.67)/12

θ = tan^-1 -2.47

θ = -67.96°

θ = 90-67.96

θ = 22.04° (to 2dp)

To determine the current, we will use the relationship

V = IZ

I =V/Z

Given V = 12V

I = 29.93/12

I = 2.494A (3dp)

The east-west row planting orientation is preferred to maximize light absorption of
Katyanochek1 [597]

Answer: True

Explanation:

The east-west row planting orientation helps in the maximize the light absorption by plants which then brings about an efficient photosynthesis activity.

Also, it helps in the shading of weeds that can be found in the inter-row space. Also, it brings about an improvement on drop yield crop yield.

Therefore, the answer to the above is true.

An operator decided to develop a subsea drill center of 4 oil wells. The production from the drill center is to be transported t
Vikki [24]

Answer:

The possible options the operator can choose from for the manifold system are;

1) Cluster manifold system

2) Template manifold system

Explanation:

Given that a subsea drill center is to be used for the development of the field that have four wells, we have;

1) Clustered system

In the clustered system design, the wells are situated and drilled around the designated area where the manifold will eventually be installed, such that there is increased flexibility in investment such that the economy of the development can be factored in as the field is being developed favoring the suitability of the cluster field system for a field with a few number of wells such as the one in question.

However for shallow wells and in a situation of high financial uncertainties such that the wells can be drilled at the same time the the manifolds are being constructed saving costs of waiting for the template the cluster manifold system will be more appropriate

Also as there are few wells the cluster manifold system can be more cost effective in terms of scheduling and resource allocation.

2) Template System

In the template manifold system design, the wells are drilled in a prefabricated well template housing which will hold the completion tools of the well, As such the well completion are well arranged and interconnected within the template design

Whereby the aim is for a fast an economic as well as a well built system, then the right choice is the template manifold design where there is direct flow from the wells to the template manifold improving flow assurance, and reducing installation costs as the system does not require jumper installation which is costly
