The boundary conditions are 40kW of total heat over the pipe wall,inlet volume flow of 0.004 m^3/s at temperature of 20C,and outlet of 0 pressure.The temperature difference between the wall and the bulk of the water can be computed via well known correlations such as Gnielinski correlation.Screen Wicks - Heat Pipe Manufacturer SuppliersAnnular heat pipes have screen wicks,since they are more flexible as the heat pipe is heated and cooled.Screen wicks are specified by mesh size.For example,a 100 x 100 mesh screen means 100 wires per inch in both directions.Related searches for stock number heat number of pipepipe heat number searchheat numbers steelSome results are removed in response to a notice of local law requirement.For more information,please see here.12345NextNational Stock Number NSN 4710-00-278-3294,National Stock Number 4710-00-278-3294 National Stock Number (NSN) 4710-00-278-3294,or NIIN 002783294,(tube,metallic) was assigned January 1,1961 in the Federal Logistics Information System (FLIS).This NIIN is Available for Manual Assignment.
