Zekeman,
Thanks for taking time to reply. The information comes from Table 10.2.4 "Saturated steam pipeline capacities in kg/h for different velocities (Sch. 40 pipe)", The Steam & Condensate Loop, Spirax-Sarco, 2008. Throughout the preceding chapter, they refer to 40 m/s as the practical...
Hacksaw,
Thanks for the valuable input. I know the steam is quite wet by the time it reaches the HX, as this appliance is the furthest from the boiler: nearly 300 feet away. The condensate load post-HX is very heavy & usually waterlogs the lower portion of the HX until pressure is sufficient...
I have a plate heat exchanger designed to consume 2533 lbs of steam per hour at 249 deg F (roughly 14.5 psig). My boiler (under ideal conditions) delivers steam to this HX at ~338 deg F, 100 psig, through a 1" sch. 40 line. I'm trying to determine how many pounds of steam are actually being...
I guess I should boil this down more succinctly. I know the values are correct. Where I'm uncertain is in the interpretation of the static head pressure value, 436.8 mmHg, which is equivalent to the 14 ft of lift in my application. Is the 436.8 mmHg absolute, or must it be subtracted from 760...
I'm working on a pump for a suction lift application & want to insure that the pressure at the pump inlet remains high enough to prevent vaporization of the liquid. The liquid is 50% sulfuric acid at ~25 deg C. Vapor pressure at this temp is 8mmHg. The static suction pressure will be 58.2 kPa...
I've been trying to find guidelines for maximum recommended fluid velocity in a 2" Sch. 5S tubing system. We have pumps capable of 100 GPM (water) output, resulting in about 8 ft/s velocity & 5 PSI pressure drop per 100 ft. Besides the increased load on the pump motors & potential for...
