Q2. Pump cavitation reason how u can sloved that problem. Distillation plate design method
Ans. 
Pump cavitation can be caused by low pressure or high temperature. It can be solved by increasing pressure or reducing temperature.
• Pump cavitation occurs when the pressure in the pump drops below the vapor pressure of the liquid being pumped.

• This can be caused by low pressure or high temperature.

• To solve the problem, you can increase the pressure or reduce the temperature.

• Other solutions include increasing the size of ...read more

Q3. Steam ejector working as pressure sensitivity
Ans. 
Steam ejector works based on pressure sensitivity.
• Steam ejector uses high-pressure steam to create a vacuum by entraining and compressing low-pressure gas or vapor.

• The pressure difference between the high-pressure steam and low-pressure gas or vapor causes the gas or vapor to be drawn into the ejector.

• The steam ejector is commonly used in refrigeration, distillation, and vacuum systems.

• The efficiency of the steam eject...read more

Q2. Difference between CSTR and PFR, Pumps ,Heat Exchanger.
Ans. 
CSTR and PFR are types of reactors, pumps are used to move fluids, heat exchangers transfer heat between fluids.
• CSTR (Continuous Stirred Tank Reactor) has a constant volume and operates under steady-state conditions.

• PFR (Plug Flow Reactor) has a varying volume and operates under unsteady-state conditions.

• Pumps are mechanical devices used to move fluids from one place to another, like centrifugal pumps or positive displ...read more

Q3. What is cracking
Ans. 
Cracking is a process in which complex hydrocarbon molecules are broken down into simpler molecules.
• Cracking is a refining process used to convert large hydrocarbon molecules into smaller, more valuable ones.

• It is done by breaking the carbon-carbon bonds in the molecules.

• Examples include catalytic cracking and steam cracking.

Q4. What is Reforming
Ans. 
Reforming is a process used in the petroleum industry to convert low-octane naphtha into high-octane gasoline.
• Reforming involves rearranging the molecular structure of hydrocarbons to increase their octane rating.

• It is typically done using a catalyst at high temperatures and pressures.

• The process can also produce hydrogen gas as a byproduct.

• Reforming is an important step in the production of gasoline and other fuels in...read more

Q5. What is range and approach of cooling tower
Ans. 
The range of a cooling tower refers to the maximum distance at which it can effectively cool air, while the approach is the temperature difference between the cooled water and the entering air.
• Range of a cooling tower is typically around 5-20 degrees Fahrenheit

• Approach of a cooling tower is usually around 8-15 degrees Fahrenheit

• The range and approach of a cooling tower can vary based on factors such as design, size, an

Q1. Modes of Heat transfer
Ans. 
Modes of heat transfer include conduction, convection, and radiation.
• Conduction is the transfer of heat through a material without any movement of the material itself.

• Convection is the transfer of heat through the movement of fluids, such as air or water.

• Radiation is the transfer of heat through electromagnetic waves, such as the heat from the sun.

• Examples of conduction include touching a hot stove or holding a cold dr...read more

Q2. Design of distillation coloumn
Ans. 
Design of distillation column involves determining the number of trays, column diameter, and feed location.
• The number of trays is determined by the separation required and the reflux ratio.

• Column diameter is determined by the vapor and liquid flow rates.

• Feed location is determined by the composition of the feed and the desired product purity.

• Other factors to consider include pressure drop, heat transfer, and material s...read more
