I did my math and because of my design, apparently I need 88.7psi of propane into my chamber. Since a regular propane bottle is ~90psi in warm climate can I just skip tryng to meter it altogether and just stick a ball valve after the bottle and let it direct into the chamber?
By my math:
62" barrel, 3" sch40 PVC
42" chamber, 4" sch40 PVC
Vol of fuel for 42" chamber of 4"sch40 PVC needed= 348.2ml
Meter volume will be = 56.9ml
Pressure in BAR on regulator = 6.119 (88.748psi)
Is it going to need ~89 psi into the chamber, can I just let the 90psi from the tank right into it without blowing anything up? It'd be awesome to make some things unecessary and save weight and less parts.
Lert me know what you all think.
