Cooling Water System Design

(pdf) design calculations for the cooling water …,the cooling water system is primarily used to ensure that the temperature of the main engine is kept within the acceptable limit for maximum performance during operations. the system also to design a liquid cooled system - semi-therm,•air cooling is limited by specific heat. to dissipate large amounts of power, a large mass flow rate is needed. −higher flow speed, larger noise. •liquid cooling is able to achieve better heat transfer at much lower mass flow rates. −lower flow speed, lower noise. •heat transfer coefficients for air an liquid flows are orders of magnitude.
