There are several types of reactors used in various industries, including nuclear reactors, chemical reactors, and biological reactors.

• Nuclear reactors are used to generate electricity through nuclear fission, such as pressurized water reactors (PWR) and boiling water reactors (BWR).

• Chemical reactors are used in the production of chemicals and pharmaceuticals, such as batch reactors, continuous stirred-tank reactors (C...read more

Types of couplings include rigid, flexible, fluid, and magnetic couplings.

• Rigid couplings provide a solid connection between two shafts, allowing for no misalignment.

• Flexible couplings accommodate slight misalignment and reduce shock and vibration.

• Fluid couplings use hydraulic fluid to transmit power and allow for torque multiplication.

• Magnetic couplings use magnetic fields to transmit torque without physical contact.
