In general, using these rules or fan laws, once we know the performance of a given fan under set specified operating conditions, variations in the performance can be predicted with reasonable levels of accuracy. FluidFlow software considers the effects of compressibility, suction pressure variation, etc whilst also solving the fan laws ensuring a high level of accuracy. FAN NOISE PREDICTION The sound power produced by centrifugal and axial fans can be approximated by a simple equation (ref. For constant pressure â fan speed, air-delivery and horse-power absorbed vary inversely as the square root of the density. Brake Horse Power - BHP. Knowing the performance of a given fan under set specified operating conditions, variations in the performance can be predicted according to the fan laws. CalQlata has tried to keep the operation of this calculation option as simple as possible, given that it is recommended for general purpose calculations only and not for actual purchase specifications (see Fan Calculator â Technical Helpbelow). Also, it’s worth noting that changing fan accessories such as inlet dampers, inlet boxes will change the fan performance curve from the standard. After each component has been evaluated for pressure loss, the total summation is used to evaluate the fan brake horsepower. This should, therefore, be considered before considering or applying the fan laws. Equation Overview Short Long This calculator can be used to determine the centrifugal pump brake horsepower (BHP) for a given flow rate (Q), head (H), specific gravity (S.G.), and efficiency (Eff). Due consideration is therefore recommended on evaluating any applied “safety factors” against the actual cost penalty incurred. For a four cylinder engine,

Earlier it was used to measure steam engine power output compared to the power of draft horses. This fan curve is usually measured at “standard” or other stated conditions. MHP=(CFM*TSP[in.wg])/6,356 â¢ Q = Air flow rate in CFM. â¢ Pt = Total pressure, in-WG. This duty-point is at airflow Q1 which is delivered against pressure P1. HP=BHP*(1/(motor efficiency)) 2. We have also developed bespoke products for Fortis BC, Sterling Fluids Systems & Weir Group. Thermal analysis included with comprehensive databases. The performance of a centrifugal fan, axial fan or blower is often given as a series of pressure, efficiency and shaft power characteristic curves plotted against air flow rate for specified values of speed, air density, and fan dimensions. The fan sound power is evaluated from the total pressure loss as shown by Equation 3 (Reference 2).
