Boiler horsepower equals 9809.5 watts.
It was used for rating steam boilers and is equivalent to 34.5 pounds (about 15.6 kg) of water evaporated per hour at 212 degrees Fahrenheit (100 degrees Celsius).
dp=Cah(1/T0-1/T1)
psi is Pounds per Square Inch, and is a measure of the pressure inside the boiler.
Boiler can be classified as below
Atmospheric Fluidized Bed Combustion Boiler (AFBC boiler) is a type of operational boiler. In a AFBC boiler a little more fluidized bed combustor is added than a conventional shell boiler.
Boiler have minimum pressure 28 bar as per. Indian boiler act.so p c xan not call a boiler
Boiler power is not determined in megawatts. A boiler horsepower is determined as 33000 btus. That is equivalent to 34.5 pounds of steam from and at 212 F. Conversion of boiler conditions (factor of evaporation) output and horsepower to atmospheric steam conditions is the norm for determining boiler horsepower. The ASME code contains several methods for determining boiler horsepower. Megawatts are a determination of turbine-generator output.

400hp is 1,017,773 Btu
The energy required for a boiler to produce 1kg of steam is dependent on the size and pressure exerted by the boiler. The output is described as the boiler horsepower. Once the dimensions are known calculation is a simple ratio.
Electric boilers require approximately 3 1/2 kilowatts per boiler horsepower. Fuel oil typically produces approximately 3.5 boiler horsepower per gallon of oil burned*. *This depends on several factors in boiler design, furnace design and fuel heat content.

You must mean "why can i model a boiler and pump" as an electrical circuit. The answer is "elecrical components can be arranged to correspond to a useful mathematical model for the boiler and pump."
Horsepower.
Boiler loads, or the capacity of steam boilers, are often rated in boiler horsepower, lbs of steam delivered per hour, or BTU. Large boiler capacities are often given in lbs of steam evaporated per hour under specified steam conditions. Since the amount of steam delivered varies with temperature and pressure, a common expression of the boiler capacity is the heat transferred over time expressed as British Thermal Units per hour.
psi is Pounds per Square Inch, and is a measure of the pressure inside the boiler.
By Horsepower if you mean engine ouput ? If so these days it is often expressed in kilowatts rather than horsepower (1HP=0.746kW)
