WebJul 28, 2024 · The coefficient of friction between the belt material and the pulley is 0.5. If we require a power of 100 Watts (Nm/s) while the input is rotating at a rate of 1000 rpm and … WebNov 17, 2016 · where ρ is fluid density, v is speed through the fluid, A is an appropriate area and C d is the relevant drag coefficient, which depends on the shape of the object relative to the direction of flow. As you can see, viscosity does not enter this calculation. The only difficulty is deciding what values to use for A and C d.
