Q1. Types of heat exchanger and its difference from each other
Ans. 
Heat exchangers are devices that transfer heat between two or more fluids.
• Types of heat exchangers include shell and tube, plate and frame, and finned tube.

• Shell and tube heat exchangers are the most common and consist of a shell with tubes inside.

• Plate and frame heat exchangers use plates to transfer heat between fluids.

• Finned tube heat exchangers have fins on the outside of the tubes to increase heat transfer.

Q2. Whats reflux in distillation
Ans. 
Reflux is the process of condensing and returning the vapors that rise from the distillation process back into the distillation flask.
• Reflux helps to improve the efficiency of the distillation process by preventing the loss of volatile components.

• It is achieved by using a condenser to cool the vapors and return them to the distillation flask.

• Reflux is commonly used in the production of high-purity chemicals and fuels.

• I...read more

Q3. Pump curve and its significance also cavitation and primming
Ans. 
Pump curve shows the relationship between flow rate and head. Cavitation and priming are common issues in pump operation.
• Pump curve is a graph that shows the performance of a pump at different flow rates and heads.

• It helps in selecting the right pump for a specific application and also in troubleshooting pump problems.

• Cavitation occurs when the pressure in the pump drops below the vapor pressure of the liquid, causing ...read more

Q2. What is the Pressure units.?
Ans. 
Pressure units are used to measure the force exerted on a surface per unit area.
• Pressure is typically measured in units such as pascal (Pa), bar, psi, or atmosphere (atm).

• 1 pascal (Pa) is equal to 1 newton per square meter (N/m²).

• 1 bar is approximately equal to atmospheric pressure at sea level (1 atm).

• 1 psi (pound per square inch) is equal to approximately 6895 pascals (Pa).

Q3. What is the fire trangle.? And diamonds.?
Ans. 
The fire triangle is a model that explains the three elements required for a fire to start and continue. Diamonds are a form of carbon that is highly valued for their beauty and durability.
• The fire triangle consists of three elements: fuel, heat, and oxygen.

• If any of these elements are removed, the fire will be extinguished.

• Diamonds are formed deep within the Earth's mantle and are brought to the surface through volcan...read more

Q5. What is the Bernoulli equation.?
Ans. 
The Bernoulli equation relates the pressure, velocity, and elevation of a fluid in a streamline.
• The Bernoulli equation is a fundamental equation in fluid dynamics.

• It states that the total energy of a fluid remains constant along a streamline.

• The equation relates the pressure, velocity, and elevation of the fluid.

• It is derived from the principle of conservation of energy.

• The equation is commonly used in various applicat...read more
