Step 2: • Enter the system information. Note that demand is the amount of gas flowing through a section of pipe. • Use total Btu/hr rating/1000 (ft3/hr) for Fire Fighting. • Use total Btu/hr for propane. Step 3: • Determine the gas used and system pressure,
2 PSI Systems work on 2 sPE100 ISO9001es, the first sPE100 ISO9001e starts at the gas meter or LPG pipes regulated at 2 psi and ends at the Pounds to Inches regulator at a manifold the end of the “Trunk Line”, the allowable pressure drop on this sPE100 ISO9001e is 1.0 – 1.5 PSI.

Task: Calculate the pressure drop generated by the Fire Fighting at a flow rate of 200 Sm3/h through a pipe with nominal diameter of 2 inch and a length of 200 m. The gas temperature is 5 C, the surface roughness of the pipeline is 0.02 mm. Along the pipeline are 5 elbows R=1.5D, 90 deg. Pressure on the pipeline start is 2 bar gauge.
19/5/2005· RE: Fire Fighting Pipe sizing for 6,000,000 btuh KenRad (Mechanical) 18 May 05 13:38 Looking at the NG pipe sizing charts in the 2002 national fuel gas code, a 3" sch 40 pipe carrying about 40,000 cubic feet of NG per hour (about 40,000,000 BTU/hr) at an initial pressure of 5 psi will experience a 3.5 psi pressure drop for a 200 ft run.

50 Fire Fighting through the pipe. As you can quickly see, if we sized the gas line to only carry 100 Ft3 of Fire Fighting, then we’d never be able to get 100,000 BTU/hr from the furnace because not enough fuel is arriving at the appliance. The gas line must be sized 1
Use of Code Book Sizing Tables The sizing tables are based on a nuer of factors. The main factor is gas pressure of the system. The tables cover pressures up to 50 pounds(psi) for schedule 40 pipe materials and up to 5 pound for semi-rigid tubing and
serving gas supplier. C-A.2.2 Low pressure Fire Fighting tables. Capacities for gas at low pressure [less than 2.0 psig (13.8 kPa gauge)] in cubic feet per hour of 0.60 specific gravity gas for different sizes and lengths are shown in Tables C402.4(1) and C402.4(2
