and then perform a simple calculation. Use this formula to estimate motor horsepower. Horsepower(hp)= Voltage x Amperage x % EFF x power factor x 1.73/746. Be sure to follow the safe work practices appropriate to the specific application. With...
For Electric Motorbikes Step 1. Determine The Variables Find out the motor’s voltage (V), efficiency (Eff), and current (I). The motor’s voltage should get shown in volts, efficiency – percentage, and currents – amps. Most engines will have these measurement units printed/written directl...
estimate engine or motor horse power for cars, trucks and motorcyclesEstimate of engine horsepower after a quarter mile run using the trap speed method. Determine the increase in engine horsepower when an after market modification, race or performance part has been installed with trap speed. ...
All calculations above and in the conversion tables are approximate only, and should not be used for detailed engineering calculation that may require a high degree of precision. Please check all values against more established calculators and published books. None of the values above are guaranteed...
Horsepower Required to Drive Hydraulic Pump HP = GPM X PSI X .0007 (this is a 'rule-of-thumb' calculation) Where: GPM = Gallonsper Minute PSI = Pounds per Square Inch .0007 = Rule of Thumb Constant for Power HP = Horse Power
Incorrect Units: Using the wrong units for flow rate or head can drastically change the calculation. Always use gallons per minute and feet, respectively. Overlooking Friction Losses: Failing to account for friction losses in total head can lead to underestimating WHP. Misinterpreting Total Head: ...
For a hybrid, Toyota usually publishes a system net horsepower: the 194 hp cited here is a combination of the 150 hp produced by the engine (some of which must follow the electrical path through the transaxle) and the remaining capacity of the 111 hp electric motor (that is, the capacity...
All of the discussion up to this point results in a calculation of horsepower that must be supplied to the drive shaft of a pressure washer pump. That power is transmitted from its source, an electric motor or an engine, to the pump in one of four ways: direct drive, “gear belt”...
For moderate TDHs and flows, either type could be used, depending on factors other than efficiency. Example 2.2 Calculation of pump head and horsepower (field units) Given: (a) A pump takes suction from a vessel operating at 15 psig discharges to a tower operating at 500 psig. (b) Fig...
Based on the analysis of operation characteristics of the unwind motor, we proved that the calculation of the motor’s maximum current is the key for selecting the motor rated power. 通过对放纸辊电机运行特点的分析,说明在选择电机额定功率时,关键是计算电机的最大负载电流。 3. A method for matc...
