Forced or pump cooling:
-This system is used in large number of vehicles like car, buses, trucks and other heavy vehicles. Here circulation of water takes place with convection currents help by a pump.
-The water or coolant is circulated through jackets around the parts of the engine to be cooled, and is kept in motion by a centrifugal pump, driven from the engine through V-belt.
Limitation
-Cooling is independent of temp.
-Engine is overcooled (when range of temp.=75-900C)
-Can be overcome by using thermostat
