Bimetallic steam trap ( BST )

As the name implies, bimetallic steam traps are constructed using two strips of dissimilar metals welded together into one element. The element deflects when heated. (Figure 3):
There are two important points to consider regarding this simple element:

Balanced pressure steam trap ( BPST )

Balanced pressure steam trap with replaceable capsule

A large improvement on the liquid expansion trap is the balanced pressure trap, shown in Figure 2 Its operating temperature is affected by the surrounding steam pressure. The operating element is a capsule containing a special liquid and water mixture with a boiling point below that of water. In the cold conditions that exist at start-up, the capsule is relaxed. The valve is off its seat and is wide open, allowing unrestricted removal of air. This is a feature of all

Liquid expansion steam trap ( LEST)

 Liquid expansion steam trap

This is one of the simplest thermostatic traps and is shown in Figure 1 An oil filled element expands when heated to close the valve against the seat. The adjustment allows the temperature of the trap discharge to be altered between 60°C and 100°C, which makes it ideally suited as a device to get rid of large quantities of air and

WHAT IS A BATTERIES AND ITS INVENTION

There are a lot of different kinds of batteries, but they all function based on the same underlying concept.In the modern era, electrical energy is normally converted from mechanical energy, solar energy, and chemical energy etc.  “A battery is a device

Electrical Current Formulas in DC Circuit

I=V/R

I = P/V

I = √P/R

*Where

I = Current in Amperes (A)

V = Voltage in Volts (V)

P = Power in Watts (W)

R = Resistance in Ohm (Ω)

Electrical Current Formulas in Single Phase AC Circuit

I = P / (V x Cosθ)

Ohm’s Law with simple example

The relationship between Current through and Voltage across a conductor was first discovered by a German scientist George Simon Ohm. This relationship is called Ohm’s Law and be stated as;

The Current “I” flowing through a conductor is directly proportional to the potential difference i.e. Voltage “V” across its ends provided the physical conditions (i.e. temperature, strain, etc) do not change.

In other words;

In any electric circuit, the Current “I” is directly proportional to the applied Voltage “V” and inversely proportional to the

What is Motor Efficiency & How to improve it?

Electric motor is a type of machine which converts electrical energy into mechanical energy using the interaction between magnetic field and current in its winding to produce/generate force in the motor. If we actually reverse this process then mechanical energy is converted into electrical energy and that is done by generators .Electromagnetism Is the main phenomenon that is used by motors.
