Some Basic Physics Formula's and Definations

Today, we are going to be talking about certain formulas an desalination  you need t know especially when it come to carring out sizing.

 Ohm's Law :Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference across the two points.The  formula that defines the relationship between resistance(R), voltage(V), and current(I) is V=IR,

Power: This is the rate at which energy is transferred, used, or transformed. Electrical power is rated in Watts and is equal to the product of Voltage (v) and current (I). As in P = V I.

Current This can be defined as the flow of electrons in an electrical circuit. it is measured in amperes (A)

Voltage: This is the difference in electrical potential that exists between two points in a circuit.
It is measured in volts.(v)

Watt-Hour: This is a unit of energy equivalent to one watt (1 W) of power expended for one hour (1 h) of time. - 1 watt produced or consumed for a period of 1 hour. it can be represented as (Wh)

Resistance: This can be defined as the opposition to the flow of current. it is measured in ohms

Since some of this definitions may seem a little abstract to some people, let me bring the above definitions home a little so you can have a better understanding of what am talking about.

Assuming we have water flowing from an overhead tank into the house for domestic use, then we would define the following as thus:

Voltage: This would be the equivalent of the water pressure in the pipe.

Current: This would be the equivalent of the rate of water flowing through the pipe

Power: This Could be defined as the Total amount of water flowing through the pipe based on the water pressure and the rate of flow.

The following formulas can be used to calculate the power flowing through a circuit

Power= V²/R =  I²/R  =  V x I

Where:

V = Voltage

R = Resistance

I = Current
