Q1. Tell me about refrigeration cycle
Ans. 
Refrigeration cycle is a process in which a refrigerant absorbs heat from a low-temperature space and rejects it in a high-temperature space.
• The refrigeration cycle consists of four main components: compressor, condenser, expansion valve, and evaporator.

• The refrigerant starts as a low-pressure gas in the evaporator where it absorbs heat from the space being cooled.

• The compressor then compresses the refrigerant into a h...read more

Q2. How work of four stroke cycle engine?
Ans. 
Four stroke cycle engine works by completing four distinct processes - intake, compression, power, and exhaust strokes.
• Intake stroke: Air-fuel mixture is drawn into the cylinder as the piston moves downward.

• Compression stroke: The intake valve closes and the piston compresses the mixture, preparing it for ignition.

• Power stroke: The spark plug ignites the compressed mixture, causing an explosion that drives the piston d...read more

Q2. What ispressure
Ans. 
Pressure is the force applied per unit area on a surface, influencing fluid dynamics and mechanical systems.
• Pressure is measured in units such as Pascals (Pa), atmospheres (atm), or pounds per square inch (psi).

• In fluids, pressure increases with depth due to the weight of the fluid above.

• Example: Atmospheric pressure at sea level is approximately 101.3 kPa.

• In medical terms, blood pressure is a critical measure of cardi
