Cooling and Heating Equations - Engineering ToolBox

The relative humidity of the air is 70% at the start and at the end of the cooling process. From the psychrometric chart we estimate the water content in the hot air to be 45 grains water/lb dry air and the water content in the cold air to be 27 grains water/lb dry air. Using (2b) the latent heat removed from the air can be calculated as

Sizing a Closed Water System Water Volume | Heating Chilled

Where capacities are not given for heating systems allow eleven litres of capacity for every KW of boiler output (or 10000 gallons for every 1.5 million BTU). These systems should be protected from corrosion and scale by the addition or Nitrite Molybdate or Tannin inhibitors. NB: Where boiler is providing heating for hot water as well subtract this load from the calculation.

Heating Systems Flow Rates - Engineering ToolBox

A water circulating heating systems delivers 230 kW with a temperature difference of 20 o C. The volumetric flow can be calculated as: q = (230 kW) / ((4.2 kJ/kg o C) (1000 kg/m 3) (20 o C)) = 2.7 10-3 m 3 /s. The mass flow can be expressed as: m = (230 kW) / ((4.2 kJ/kg o C) (20 o C)) = 2.7 kg/s. Example - Heating Water with Electricity
