British thermal unit per hour. Definition: The British thermal unit per hour (symbol: Btu/h) is a United States customary system unit of power. This unit is often abbreviated as simply "Btu," which is the same abbreviation used for British thermal units, a measurement of heat.
A ton of refrigeration (TR or TOR), also called a refrigeration ton (RT), is a unit of power used in some countries (especially in North America) to describe the heat-extraction capacity of refrigeration and air conditioning equipment.

but could reach a full plant emergency rate of 700 megagrams per hour (Mg/hr) (750 tons/hr). Normal process blowdowns may release 450 to 900 kg/hr (1000 - 2000 lb/hr), and unit maintenance or minor failures may release 25 to 35 Mg/hr (27 - 39 tons/hr). A 40 molecular weight gas typically of
The calculation of normal and standard gas flowrates (NM 3 /hr and SM 3 /hr calculation), first requires the normal and standard conditions to be fixed. Normal temperature and pressure conditions are already defined in the problem statement and standard temperature and pressure conditions defined by NIST are to be used.

How to Convert GPM to Cooling Rate in Tons. Factories use heat exchangers or chillers to regulate an area's temperature. The machine absorbs heat from an area that produces it and carries it to a different location. The medium that carries the heat is a refrigeration fluid that absorbs and releases heat as it

HVAC CHILLED WATER DISTRIBUTION SCHEMES A chilled water system is a cooling system in which chilled water is circulated throughout the building or through cooling coils in an HVAC system in order to provide space cooling. The principal objectives of chilled water pumping system selection and design are to
Diferent flow rate units conversion from pound (water mass) per hour to gallons US per minute. Between lb/h and gal/min measurements conversion chart page. Convert 1 lb/h into gallon US per minute and pounds (water mass) per hour to gal/min.
For the low-pressure steam typically used in heating systems, that ratio is 1,194 BTUs for every pound of steam the system provides. If your boiler supplies 400 pounds of steam per hour, for example, you would multiply 400 pounds by 1,194 to arrive at a figure of 477,600 BTUs.

Volume and Mass Flow Calculations for Gases Many times it is necessary to calculate either mass flow or volumetric flow for your application. This same calculation method can also be used to determine the volume at some other set of conditions.
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.
