Brake Horsepower [HP] = Flow Rate [GPM] × Pressure [PSI] / (1714 × Efficiency) Example: Flow Rate = 100 GPM Operating Pressure = 500 PSI Efficiency = 93% 100 [GPM] × 500 [PSI] / (1714 × 0.930) = 31.37 HP These calculations and the information provided on this page is for reference only.
Reynolds number is calculated using relation, Re = D 2 Nρ/μ and a new Pumping number is determined using generic agitator curves. All previous steps are repeated, till correct speed is determined. Power Number is determined based on Reynolds number from generic agitator curves. Power, P is calculated using definition of power number.

Calculation of the quantity of water to be evaporated is explained below with a sample calculation. If the throughput of the dryer is 60 kg of wet product per hour, drying it from 55% moisture to 10% moisture, the heat requirement is: 60 kg of wet product contains 60 x 0.55 kg water = 33 kg moisture and 60 x (1 - 0.55) = 27 kg bone-dry product.

To ensure you are sizing your Rotary Phase Converter correctly please add the two HP ratings together and input that into our Phase Converter Wizard or contact our office at 1-888-743-6832 to talk with one of our sales associates Calculations: • 240v amps / 2.8 = 240v HP • KW * 1.342 = HP • KVA = HP • Watts / 1000 * 1.342 = HP
inside the dryer (Perry and Green, 1999). The number and format of flights influence the amount of material present in the rotary dryer. Perry and Green (1999) suggest that the volume occupied by the load of solids in the rotary dryer should be between 10 and 15% of the total dryer volume. Figure 2 presents a scheme of the flights with two
8. Advantages 1- The rotary vacuum drum filter is a continuous and automatic operation, so the operating cost is low. 2- The variation of the drum speed rotating can be used to control the cake thickness. 3- The process can be easily modified (pre-coating filter process). 4- Can produce relatively clean product by adding a showering …

33,000 lb-ft / min = lb-ft. x 2π x revolutions/min. Divide each side by 2π (6.28315) and you get 5,252 lb-ft / min = lb-ft. x revolutions / min. Next divide each side by 5252 and you end up with this equation: 1 Horsepower = Torque x R.P.M. / 5252. Because of this math, lb-ft of torque and horsepower will always be the same at 5,252 RPM.
