In other words, it takes 970.2 Btu to convert one pound of hot water into steam-- 'from and at 212.' This 970.2 Btu times the 34.5 pounds per hour in the definition of one boiler horsepower equals 33,472 Btu per hour. Generally, it has been the practice to round out the figure to33,470 Btu/hr equals one boiler horsepower.

May 04, 2019 · Multiply the torque by the engine speed. You will be using the formula (RPM * T) / 5252=HP, where RPM is the engine speed, T is the torque, and 5,252 is radians per second. The first calculation you want to do is multiply the torque and the engine speed. For example, a Porsche generates 480 of torque at 2,500RPM.

Base flow = Boiler maximum capacity horsepower X 0.069 X C • C = 1.5 for On/Off intermittent operation • C = 1.15 for continuous feed operation 29

To find hydraulic horsepower, use the equation: HP = (PSI X GPM) / 1714. PSI = Pressure in Pounds per Square Inch. GPM = Flow Rate in Gallons per Minute. Example: Calculate hydraulic horsepower when pressure is 2000psi and flow rate is 20GPM: Horsepower = (2000 x 20) / 1714. Calculated out this gives a hydraulic horsepower of 23.34.

Apr 24, 2017 · Converting BTU to Horsepower. For example, the power of a boiler is often expressed in BTU, and car engines' power is often expressed in horsepower. To convert BTU per hour to horsepower use the following equation: Power (Horsepower) = Power (BTU per hour) x 2,545.

The current equivalency is either 41,844 btu/hr heat input or 33,475 heat output from burners. Efficiency of the burners is assumed 80%. Now if you have an older fire tube boiler, the boiler horsepower is based on heating surface and the equivalency is 1 BoHp= 10 sq.ft. of heating surface.

water horsepower: Q = flow rate or discharge: H = total head: n = pump efficiency: BHP = brake horsepower: NPSH = net positive suction head: V = velocity of fluid or liquid: p = impeller inlet pressure: p v = vapor pressure of fluid or liquid: SW = specific weight of fluid or liquid: g = acceleration of gravity

A common definition of one boiler horsepower is the amount of energy required to produce 34.5 pounds (15.65 kg) of steam per hour at pressure and temperature 0 psig (0 bar) and 212 o F (100 o C) - with feed water at pressure 0 psig and temperature 212 o F.

Boiler Horsepower. Boiler horsepower is used to measure the power of a boiler to generate steam. One boiler horsepower is equal to the power needed to evaporate 34.5 pounds in one hour. Boiler horsepower can be abbreviated as hp(S), for example 1 boiler horsepower can be written as 1 hp(S).

Diferent power units conversion from Boiler horsepower to megawatts. Between bhp and MW measurements conversion chart page. Convert 1 bhp into megawatt and Boiler horsepower to MW.

One boiler horsepower = 34.5 lbs/hr of steam (or water) from and at 212o F. We also know that one-gallon of water weighs 8.37 lbs. To calculate the storage tank needed use the following formula: BHP X 34.5 ÷ 8.337 lbs ÷ 60 min. X 10 = minimum useable capacity in gallons.

The receiver tank should be able to hold five minutes worth of condensate for boilers up to 200 BHP and 10 minutes of condensate for boilers over 200 BHP. An additional 33 percent should be added as a safety factor. One BHP (Boiler Horsepower) will produce 0.069 gallons per minute of condensate. Developing a formula results in:

Boiler horsepower. Boiler horsepower is a boiler's capacity to deliver steam to a steam engine and is not the same unit of power as the 550 ft-lb/s definition. One boiler horsepower is equal to the thermal energy rate required to evaporate 34.5 lb of fresh water at 212 °F in one hour.

A boiler horsepower is more than 13 times larger than mechanical horsepower (~engine output). 1 BTU (International Table) per Hour: Approximately 0.293 071 Watts (SI).

Estimating horsepower by air flow. For example, a stock 1,600 head flows about 61 CFM. Therefore, the most you could expect with bolt-on modifications would be about 88 horsepower. This calculator makes use of the formula: Horsepower = (Air flow × 1.6) × 0.9.

500 hp x 34.5 lb / hp hr = 17,250 lb / hr produced by the boiler. This is what we call the nominal boiler capacity. In reality, the operating pressure and feedwater temperature must be taken account of to calculate the real boiler capacity.

One Boiler horsepower of power converted to BTU per hour equals to 33,471.40 Btu/h. The answer is: The change of 1 bhp ( Boiler horsepower ) unit of power measure equals = to 33,471.40 Btu/h ( BTU per hour ) as the equivalent measure for the same power type. In principle with any measuring task, switched on professional people always ensure,

How to convert boiler horsepower to kilowatts [BHP to kW]:. P kW = 9.81055407 × P BHP. How many kilowatts in a boiler horsepower: If P BHP = 1 then P kW = 9.81055407 × 1 = 9.81055407 kW

Formulas and Conversion Charts. A. Boiler Formulas Boiler Horse Power (HP): BHP =(Lb/hr) * FE / 34.5 where Lb/hr is pounds of steam per hour and FE is the factor of evaporation. Cycle of Concentration of Boiler Water: CYC=Bch / FCh where Bch is ppm water chlorides and FCh is ppm feedwater chlorides.

The basic formula used for electric boilers are as given below: 10 KW = 1 BHP (boiler horsepower)1 KW = 3412 BTU/HR. 1 KW = 3.48 LB/HR steam (from & at 212 deg. F.) Amp draw (1 PH) = watts / volts. Amp draw (3 PH) = watts / (volts X 1.732) (N.E.C. requires service for 125% of amp draw.) 1 cubic foot = 7.461 gallons water.

It may use approx 24 gallon per hour to make 300 HP. 1 Gallon of fuel weighs approx 5.92 lbs and for every 1 lb of fuel burned approx 19,000 BTU’s of energy is released. So 24 gallons x 5.92 lbs = 142 pounds per hour to make 300 HP.

Mar 06, 2018 · Horsepower Formula. Boiler horsepower (BHP) is a power unit used for measuring the power output of boilers. It was widely used in the past, though it's now mostly confined to North America. 1 Boiler Horsepower = 9,809.5 W One more unit used for power measurement is hydraulic horsepower.

Horsepower is the rate of doing work, for a RR locomotive it is the rate of delivering drawbar pull. Horsepower is limited by the ability of the boiler to deliver steam at the design pressure and the rate that the cylinders can apply the steam to the pistons, and exhaust the other side.

1 watt = 0.0001019419950048 boiler horsepower; Example calculation. Force = 12,560 newtons. Distance = 45 yards. Time = 36 seconds. Result: Power = 14,356.08 watt or 14.36 kilowatt.
