Sea Water Cooling Pump Capacity

Contents

Q = Q_cooling_duty / (ρ·cp·ΔT) - cooling-water pump sized to reject engine heat at design ΔT.

Formula

$$ Q_\text{pump} = \frac{\dot Q}{c_p \Delta T \rho} $$

Symbol	Meaning	Unit	Source
$\dot Q$	Heat rejection duty	kW	engine heat balance
$ΔT$	Cooling water ΔT	K	design
$c_p$	Sea-water specific heat	kJ/(kg·K)	4.2
