6. Power Calculation

Your browser must be able to understand 'JAVASCRIPT'.

Fill out the cells in the form below and press the Calculate-button to get the results. Use a dot '.' as decimal point for the input values. Don't forget to press the Calculate-button once again after changing of input values. Note: The calculations of the power consumption, Tension T1 and Friction Factor f are estimations. The Friction Factor f is calculated by the program if you input "0" for it. T1 and the belt quality are calculated according to the sketch shown left. Multi-pulley drives are not considered.
