Cooling Power Plants | Power Plant Water Use for Cooling

The air warmed by the hot water rises up through the shell by convection (the chimney effect), creating a natural draft to provide airflow to cool the hot water which is sprayed in at the top. Other configurations include crossflow, where the air moves laterally through the water, and co-current, where the air moves in the same direction as the

Hot Water Pressure Increase in Hot Water Tanks or Boilers

Water is at its highest density at 3.98 °C = 1000 kg/m 3 or 1 g/cm 3. The correct SI unit of density of water is ρ = 1000 kg/m 3. [also FYI, 1 m 3 = 1,000,000 cm 3]; Specific weight of water = 62.4 lb/ft 3 (IU) or 9.81 kN/m 3; Specific weight of seawater = 64 lb/ft 3 (IU) or 10.1 kN/m 3 - must be all that extra salt making it more dense, so we float better in seawater than in fresh water, right?
