coyote vs road runner application
A military base spec'd and ordered an expensive 30 PSI boiler to serve a control tower. The boiler is at the foot of a 90' water column. The engineers proposed pumping up from the mechanical room, through check valves, and on the return, as it enters the boiler room, installing a big pressure reducing valve sized properly for a low pressure drop and set to 20-22 PSI. This somehow reminds me of Road Runner painting a doorway on a rock wall and running through it, and Coyote tries but splats into hard rock. Might this be so crazy it might work?
