What Is the Steam Surface Condenser Cooling Water Flow & Temperature Rise Calculator?
In thermal and nuclear power plants, surface condensers maintain high turbine exhaust vacuum (typically 5 to 10 kPa-a) by condensing low-pressure steam back into pure liquid condensate.
Circulating cooling water from a cooling tower, river, or ocean absorbs latent heat of condensation, causing a designed temperature rise (typically 7 to 12 °C).
This calculator balances condenser thermal duty against cooling water heat capacity, computing temperature rise, outlet temperature, saturation condensing temperature, and LMTD.

Assumptions & Limitations
- Condenser Heat Duty: Q = (m_steam / 3600) · h_fg (where h_fg ≈ 2400 kJ/kg under vacuum).
- Cooling Water Temp Rise: ΔT_cw = Q / (m_dot_cw · c_p) (where c_p = 4.184 kJ/kg·K).
- LMTD: ΔT_lm = (ΔT₁ - ΔT₂) / ln(ΔT₁ / ΔT₂), where ΔT₁ = T_sat - T_in, and ΔT₂ = T_sat - T_out.
