A basic rule of thumb is one boiler hp equals the evaporation

of 4.14 gal. of water in one hour.

: I am trying to figure out how much horsepower my homebuilt water tube boiler makes. But all I have found so far is calculations based on one atmosphere.

: This boiler, with the steam outlet open to the atmosphere still maintains 40psi. So going from this, when in operation, it will evaporate about 2.5 gallons of water per hour.

: Feedwater temp is 70 deg-F

: Thanks..
