Q1. What is the orifice meter and different types of valves and distillation column..
Ans. 
An orifice meter is a device used to measure the flow rate of a fluid, while valves and distillation columns are important components in process engineering.
• Orifice meter is a type of flow meter that uses a constriction in the flow path to create a pressure drop, which is then used to calculate the flow rate.

• Different types of valves include gate valves, globe valves, ball valves, butterfly valves, and check valves. Ea...read more

Q2. Types of dryers and rotameter
Ans. 
There are various types of dryers used in process engineering such as rotary, fluidized bed, spray, freeze, and vacuum dryers. Rotameter is a flow measuring device.
• Rotary dryers are used for drying materials by direct contact with hot gas.

• Fluidized bed dryers use hot air to suspend and fluidize the material to be dried.

• Spray dryers use a nozzle to atomize the liquid feed into a fine mist which is then dried by hot air.

Q2. Which method to find no of plates in distillation column?
Ans. 
The number of plates in a distillation column can be found using the McCabe-Thiele method.
• The McCabe-Thiele method involves constructing a graph of the distillation process and determining the number of theoretical plates required for separation.

• The method takes into account the vapor-liquid equilibrium data and the reflux ratio of the column.

• The number of plates can also be estimated using empirical correlations or si...read more

Q3. What is Net postive suction head?
Ans. 
Net Positive Suction Head (NPSH) is the difference between the absolute pressure at the suction of the pump and the vapor pressure of the liquid.
• NPSH is a critical parameter in pump design and operation.

• It determines whether the pump will cavitate or not.

• Cavitation can cause damage to the pump and reduce its efficiency.

• NPSH is affected by factors such as fluid properties, pump speed, and suction piping design.

• NPSH can ...read more

Q1. What is dryer and its types?
Ans. 
A dryer is a device used to remove moisture or water content from a substance or material.
• There are several types of dryers, including air dryers, rotary dryers, spray dryers, and freeze dryers.

• Air dryers use hot air to remove moisture from materials.

• Rotary dryers use rotating drums to dry substances.

• Spray dryers use a spray nozzle to atomize liquid into a hot drying medium.

• Freeze dryers freeze materials and then remov...read more
