Air - Specific Heat at Constant Pressure and Varying

Isochoric specific heat (C v) is used for air in a constant-volume, (= isovolumetric or isometric) closed system. Note! At normal atmospheric pressure of 1.013 bar - the specific heat of dry air - C P and C V - will vary with temperature. This may influence on the accuracy of air conditioning and industrial air handling process calculations.

Steam Calculators: Boiler Calculator

Mar 17, 2015· Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.

Boiler Capacity - Engineering ToolBox

Since 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 = (h g - …
