How to Calculate and Solve for the Radius of Investigation in Well Testing | The Calculator Encyclopedia The image above represents radius of investigation.

To compute for the radius of investigation, five essential parameters are needed and these parameters are permeability (k), porosity (φ), viscosity (μ), time (t) and total compressibility (CT).

The formula for calculating the radius of investigation:

rinv = 0.0325 √[Kt / φμCT]

Where:

rinv = Radius of Investigation
K = Permeability
φ = Porosity
μ = Viscosity
t = Time
CT = Total Compressibility

Let’s solve an example;
Find the radius of investigation when the permeability is 25, porosity is 18, viscosity is 12, time is 22 and total compressibility is 37.

This implies that;

K = Permeability = 25
φ = Porosity =18
μ = Viscosity = 12
t = Time = 22
CT = Total Compressibility = 37

rinv = 0.0325 √[Kt / φμCT]
rinv = 0.0325 √[25 x 22 / 18 x 12 x 37]
rinv = 0.0325 √[25 x 22 / 7992]
rinv = 0.0325 √[550 / 7992]
rinv = 0.0325 √[0.068]
rinv = 0.0325 [0.26]
rinv = 0.0085

Therefore, the radius of investigation is 0.0085 ft.

How to Calculate and Solve for the Current, Time and Quantity of Charge of an Electrolysis | The Calculator Encyclopedia The image above represents the quantity of charge.

To compute for the quantity of charge, two essential parameters are needed and these parameters are current (I) and time (T).

The formula for calculating the quantity of charge:

Q = It

Where;
Q = Quantity of charge
I = Current
T = Time

Let’s solve an example;
Find the quantity of charge with a current of 24 and time of 12.

This implies that;
I = Current = 24
T = Time = 12

Q = It
Q = 24 x 12
Q = 288

Therefore, the quantity of charge is 288 Coulombs (C).

Calculating the Current (I) using the Quantity of Charge and Time.

I = Q / t

Where;
I = Current
Q = Quantity of charge
T = Time

Let’s solve an example;
Given that the quantity of charge is 240 with a time of 14. Find the Current?

This implies that;
Q = Quantity of charge = 240
T = Time = 14

I = Q / t
I = 240 / 14
I = 17.14

Therefore, the current is 17.14 ampere.

How to Calculate and Solve for the Current, Time and Quantity of Charge | Nickzom Calculator The image above represents the quantity of charge.

To compute the quantity of charge, two essential parameters are needed and the parameters are current (I) and time (t).

The formula for calculating the quantity of charge;

Q = It

Where;
Q = Quantity of Charge
I = Current
t = Time

Let’s solve an example;
Find the quantity of charge when the current (I) is 24 amp with a time of 8 secs.

This implies that;
I = Current = 24 amp
t = Time = 8 secs

Q = It
Q = 24 x 8
Q = 192

Therefore, the quantity of charge is 192 coulombs (C).

Calculating the Current (I) of a charge using the Quantity of Charge (Q) and the time (t).

I = Q / t

Where;
I = Current
Q = Quantity of the charge
t = Time

Let’s solve an example;
Find the current of a charge with the quantity of the charge as 150 coulombs (C) and time as 15 secs.

This implies that;
Q = Quantity of the charge = 150 C
t = Time = 15 secs

I = Q / t
I = 150 / 15
I = 10

Therefore. the current is 10 Ampere (A).

What is Simple Interest?

Simple interest is a method of calculating the interest charge on a loan or bill. Simple interest is determined by multiplying the interest rate by the principal by time which is normally in years (per annual) but could be in months, days, weeks etc during the specified time frame.

Simple Interest (S.I.) = (P x r x t) / 100

Where P stands for Principal, r stands for interest rate and t stands for time.

How to Solve and Apply Simple Interest.

There are a number of different reasons that could make one want to carry out a simple interest operation. One of them being that you want to lend money to your friend to start a business and you want your money to work for you and reproduce during the course of the loan.
