SW Cooling - Pump Flow Required
Sea-water cooling-pump flow from total heat rejected, ΔT, and SW properties.
SW flow
502m³/h
Formula, assumptions, and limits
$$\dot V = \dot Q / (\Delta T \cdot c_p \cdot \rho)$$
$c_p$ seawater 4.0 kJ/kg·K. Typical ΔT 5–8 K. Tropic SW design 32 °C inlet → 40 °C outlet. Two independent SW pumps, each 100 % duty.
