  2. atmosphere cubic feet / minute to Boiler horsepower = 0.0097 bhp.
  3. atmosphere cubic feet / minute to Boiler horsepower = 0.015 bhp.

How is fan BHP calculated?

Step-1 Formulas:

  1. When total static pressure and overall efficiency are defined, fan input power is: Pf = Vf ΔPs K1 / (ηo)
  2. When motor brake horsepower is defined, input power is: Pf = BHP * K2 / ( ηe )
  3. Brake Horsepower: BHP = ( ηe * Pf ) / K2.
  4. Fan input power at part-load: Pf,pl = [(Pf,fl) (Rpl)] / 100.

How do you calculate motor horsepower from CFM?

  1. CFM To HP Formula. The following formula is used to estimate or convert CFM to HP. HP = (CFM * 1.44)
  2. CFM to HP Definition. How is CFM converted into HP? CFM can be converted into HP by multiplying the airflow by 1.6 and then multiplying that result by 0.9.

How many horsepower is a cfm?

The horsepower – Metric unit number 0.065 hp converts to 1 atm cfm, one atmosphere cubic foot per minute. It is the EQUAL power value of 1 atmosphere cubic foot per minute but in the horsepower – Metric power unit alternative.

How is HP fan motor calculated?

Fans and Blower Horsepower Equation

  1. P = (Q x p)/(229 x ) or.
  2. P = (Q x PF)/(33,000 x ) or.
  3. P = (Q x Pw)/(6356 x ) Where: P = Power, hp. Q = Flow Rate, cfm. p = Pressure, lb/in2 Pf = Pressure, lb/ft2 Pw = Water Gauge, Inches. = Efficiency coefficient. Link to this Webpage: Engineers Edge:

How is fan motor power calculated?

Divide the fan’s power consumption, measured in kilowatts, by 0.746 to convert it to horsepower. If, for instance, a fan consumes 4 kW: 4 / 0.746 = 5.36 horsepower. Multiply the result by the fan’s efficiency. If the fan operates, for instance, at 80 percent efficiency: 5.36 x 0.80 = 4.29 horsepower.

How do you calculate brake horsepower?

Calculate Brake Horsepower. We have brake horsepower equals water horsepower divided by pump efficiency percent times 100. That’s essentially the decimal equivalent of the percentage described either way. That’s the formula, brake horsepower equals water horsepower divided by the efficiency percentage times 100.

What is the formula for horsepower?

The formula for calculating horsepower using torque involves multiplying your engine’s torque and revolutions per minute and then dividing the product by 5,252.The horsepower of the Dodge Viper is 450, while the Ferrari 355 F1 runs with 375 horsepower.

What is brake horsepower (BHP)?

Brake horsepower (BHP) is the amount of work generated by a motor under ideal conditions. This work is calculated without the consideration of the effects of any auxiliary component, that may slow down the actual speed of the motor.
