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
