Learn MoreSince the amount of steam delivered varies with temperature and pressure, a common expression of the boiler capacity is the heat transferred over time expressed as British Thermal Units per hour. A boilers capacity is usually expressed as kBtu/hour (1000 Btu/hour) and can be calculated as. W = (hg - hf) m (1) where. W = boiler capacity (Btu/h, kW)

Learn MoreBoiler Horsepower - BHP. The Boiler Horsepower (BHP) is the amount of energy required to produce 34.5 pounds of steam per hour at a pressure and temperature of 0 Psig and 212 ℉, with feedwater at 0 Psig and 212 ℉. "Boiler horsepower, a unit of measurement of power of steam boilers" from Wiki.

Learn MoreConversion of units between 5 Ton Of Refrigeration (It) and Btu (International Table) Per Hour (5 and BTUIT/h) is the conversion between different units of measurement, in this case it's 5 Ton Of Refrigeration (It) and Btu (International Table) Per Hour, for the same quantity, typically through multiplicative conversion factors ( and BTUIT/h).

Learn MoreVolumetric Water Flow Rate in SI-Units. Volumetric water flow in a heating system can be expressed with SI-units as. q = h / ((4.2 kJ/kg o C) (1000 kg/m 3) dt) = h / (4200 dt) (4) where. q = water flow rate (m 3 /s) h = heat flow rate (kW or kJ/s) dt = temperature difference (o C) For more exact volumetric flow rates the properties of hot water

Learn MoreMar 17, 2015 · Step 3: Determine Blowdown Properties and Mass Flow. Using the calculated feedwater mass flow and blowdown rate: Blowdown Mass Flow = Feedwater Mass Flow * Blowdown Rate. [ Blowdown Mass Flow = 3.4 klb/hr = 96.5 klb/hr * 0.035 ] Using the Steam Property Calculator, properties are determined using Steam Pressure and Quality = 0 (Saturated Liquid).

Learn MoreMar 17, 2015 · Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure. Does not include any evaluation of any complex boiler configurations or fluctuations in operation. Energy from motors (pumps, fans, etc.) are not considered.

Learn MoreWe can determine the volumetric flow rate as follows: The flow rate will vary according to the cross-sectional area of the channel: Area = π * (Diameter) 2 / 4. Area = 3.1415926 * (8/12 ft) 2 / 4. Area = 0.349 ft 2. The area of the pipe is 0.349 ft 2. Using this information, we can determine the flow rate (Q) as follows: Q = Area * Velocity
