Differential Pressure Measurement across Baghouse

differential pressure measurement across baghouse

Differential Pressure Measurement across Baghouse is very important to determine filtering efficiency of the baghouse fan. The increased differential pressure across bag house ( bag dust collector) shows that there is jamming inside the bags. Jamming may be due to clogging of the bags. The manufacturer specifies the rated pressure drop across BDC (Baghouse dust … Read more

How to calibrate pH Electrode?

pH scale

Importance of pH Electrode Calibration The pH measurement accuracy depends on how accurate the calibration of electrodes.The calibration of pH electrode is very simple.However, the user is not aware the reasons of calibration of the pH sensor. A standard pH combination pH electrode determines the pH value by measuring the potential generated in mV (millivolts). … Read more

What is Magnetic Flux? Definition & Properties

Magnetic Flux lines

The current flows in an electric circuit. In a same way, the flux flows in a magnetic circuit. Flux is thus analogous to electric current. The Greek letter Phi or Phi suffix B is its symbol. Its symbol is Ø and  Øm.

Transformer Interview Questions & Answers Part-4

transformer interview questions and answers part-4

Transformer Interview Questions & Answers Part-4: In this section we shall discuss more questions on transformer. Why is transformer flux constant? The net MMF in the primary remains constant. When load is increased the secondary MMF(N2I2) reflects in the primary side which is just opposite to the primary flux. Thus net flux in the primary … Read more

Classification of Control Valves

control valve classification-based on motion

Classification of Control Valves : We can classify the Control valves based on the  application, function,motion,port size and failure states. According to classification of control valve, the valves are Globe Valve, Gate Valve, Butterfly Valve, Check Valve, Ball Valve, Disk Valve, Diaphragm Valve, Linear Valve,Rotary Valve. 1.Classification of Control Valves-Based on the application According to … Read more
