Online calculator to quickly determine Steam Flow Rate through Piping. 3.5 WR = h 3 − h 6 − h 9 − h 8 − h 7 − h 10 / h 3 − h 6. Cv & Kvs Values; Air Flow Rate through a Valve; Air Flow Rate through an Orifice; Condensate Load from Compressed Air; Saturated Humid Air Table; Gas. Steam flow rate when kW rating is known can be calculated as. These applications will - due to browser restrictions - send data between your browser and our server. If 50 million btu/hr are being applied to the boiler, divide by the 970.28-btu/lb to yield 51,531-lb/hr steam flow. Figure - 20. Source: ASHRAE. Properties of Saturated Steam - Imperial Units, en: condensing condensation steam heat transferred transfer. Flow Rate (lb/h) Nominal pipe size (inch) Pressure drop per 100 ft of pipe length. The downstream pressure in a houseline after the meter/regulator is in general in the. Equations displayed for easy reference. He is currently a Research Professor with the Ph.D. program at IIT.

He was a member of the UN Technical Program to China in 1991 and a Visiting Professor from Purdue in Malaysia in 1996/97 funded by the World Bank. More information can be found in our The heat transfer rate in a condensing steam flow rate of 8 kg/h (0.0022 kg/s), atmospheric pressure and temperature 100 o C - can be calculated as. Sizing Steam Pipes - in SI units (kg/h) For full table with larger dimensions - rotate the screen! In general it is common to set, The capacity of a low pressure natural gas (less than 1 psi) pipe line can be calculated with the Spitzglass formula like, For natural gas the nominal BTU/cf varies from about 900 to 1100 BTU/cf .
