Q3. What is pump and types
Ans. 
A pump is a mechanical device used to move fluids from one place to another. There are different types of pumps based on their working principle and application.
• Types of pumps include centrifugal pumps, positive displacement pumps, and specialty pumps like diaphragm pumps and peristaltic pumps.

• Centrifugal pumps work by converting rotational energy into kinetic energy to move the fluid.

• Positive displacement pumps trap a...read more

Q4. Types Of heart transfer
Add your answer
Q5. Modes of heart transfer
Ans. 
Modes of heat transfer include conduction, convection, and radiation.
• Conduction: Heat transfer through direct contact between materials (e.g. touching a hot pan)

• Convection: Heat transfer through the movement of fluids or gases (e.g. boiling water)

• Radiation: Heat transfer through electromagnetic waves (e.g. feeling the warmth of the sun)

Q1. What is mass flux and kick's law
Ans. 
Mass flux is the amount of mass passing through a unit area per unit time. Kick's law relates to the energy required for size reduction.
• Mass flux is a measure of the amount of mass flowing through a given area per unit time.

• It is commonly used in chemical engineering to describe the flow of fluids through pipes or other conduits.

• Kick's law is a relationship between the energy required for size reduction and the size re...read more

Q2. Mass flux= mass/time×area and Ja= - Dab×dca/dz
Ans. 
The question relates to the calculation of mass flux and the use of the Ja equation.
• Mass flux is a measure of the amount of mass passing through a given area per unit time.

• It is calculated by dividing the mass flow rate by the area.

• Ja is a dimensionless quantity used in the study of mass transfer.

• It represents the concentration gradient along a distance in a system.

• Ja is calculated using the diffusion coefficient (Dab)...read more

Q1. What is mass transfer
Ans. 
Mass transfer is the movement of substances from one place to another due to a concentration gradient.
• Mass transfer involves the transfer of mass or substances between phases, such as gas-liquid, liquid-liquid, or solid-liquid.

• It occurs due to differences in concentration, temperature, pressure, or other driving forces.

• Examples of mass transfer include the evaporation of water from a wet surface, the diffusion of gases...read more
