Lubrication

Finally explain the different lubrication systems in an engine, a mill and in a water pump.

Answer explanation

Different lubrication systems in an engine include splash, pressure, and combination systems. In a mill, lubrication systems can be manual, automatic, or centralized. Water pumps typically use a self-lubricating bearing system.
