Q2. What is the state when their is no effect of pressure in a pipeline
Ans. 
The state when there is no effect of pressure in a pipeline is called atmospheric pressure.
• Atmospheric pressure is the pressure exerted by the weight of air in the atmosphere.

• When the pressure inside the pipeline is equal to the atmospheric pressure outside, there is no effect of pressure.

• This state is also known as zero gauge pressure or absolute pressure.

• It is important to maintain this state to prevent leaks or burs

Q3. How to calculate the number of trays in distillation column
Ans. 
To calculate the number of trays in a distillation column, use the McCabe-Thiele method.
• Determine the desired purity of the top and bottom products

• Calculate the minimum reflux ratio using the Fenske equation

• Use the operating line and equilibrium curve to plot the number of theoretical trays

• Add a few extra trays for safety margin

• Consider other factors such as pressure drop and column diameter

• Example: A distillation colu...read more

Q5. Relief valve and where it is used
Ans. 
Relief valve is a safety device used to prevent overpressure in a system.
• It is used in various industries such as oil and gas, chemical, and power plants.

• It opens when the pressure inside the system exceeds the set limit, allowing the excess pressure to escape.

• It helps prevent damage to equipment and potential hazards to personnel.

• Examples include pressure relief valves in boilers, safety valves in pipelines, and relie

Q4. Types of testing specially Non Destructive testing.
Ans. 
Non-destructive testing (NDT) is a testing method used to inspect materials without damaging them.
• NDT is used to detect defects or irregularities in materials or structures

• Common NDT methods include ultrasonic testing, radiography, magnetic particle testing, and visual inspection

• NDT is widely used in industries such as aerospace, automotive, and construction

• NDT can also be used in medical imaging, such as X-rays and MR

Q1. Different types of pumps ?
Ans. 
Different types of pumps include centrifugal pumps, reciprocating pumps, and rotary pumps.
• Centrifugal pumps use centrifugal force to move fluids.

• Reciprocating pumps use a piston or diaphragm to create pressure.

• Rotary pumps use rotating mechanisms to move fluids.

• Other types of pumps include gear pumps, peristaltic pumps, and jet pumps.

Q3. What do you mean by Transistors?
Ans. 
Transistors are electronic devices used to amplify or switch electronic signals and power.
• Transistors are made of semiconductor materials like silicon or germanium.

• They have three terminals - emitter, base, and collector.

• Transistors can be used as amplifiers to increase the strength of a signal.

• They can also be used as switches to turn a signal on or off.

• Examples of transistor-based devices include computers, radios, a

Q5. What is the difference between SCR and GTO?
Ans. 
SCR and GTO are both power electronic devices used for switching applications, but differ in their characteristics.
• SCR stands for Silicon Controlled Rectifier and is a unidirectional device, while GTO stands for Gate Turn-Off Thyristor and is a bidirectional device.

• SCR has a higher voltage and current rating compared to GTO.

• GTO has a faster turn-off time and lower switching losses compared to SCR.

• SCR is commonly used i...read more

Q2. 2)find 3 ph induction motor current
Ans. 
The question is asking to find the current of a 3-phase induction motor.
• Three-phase induction motors have three sets of windings that are energized in a sequence to create a rotating magnetic field.

• The current in each phase of the motor can be measured using a clamp meter or a multimeter.

• The current in each phase of the motor will vary depending on the load and speed of the motor.
