How Hydropower Works. Hydropower is using water to power machinery or make electricity. Water constantly moves through a vast global cycle, evaporating from lakes and oceans, forming clouds, precipitating as rain or snow, then flowing back down to the ocean.urbines and generators convert the energy into electricity, which is then fed into the electrical grid to be used in homes, businesses, and by industry. To see a close up view of how the generator of a water turbine works, see the Hydropower Basics page.
Regards, ... Â·. Dear Sanjay, The wear rate is calculated as the specific wear rate (Wsp), which is given as follows, Wsp=V/LD mm3/N-m. where V, L and D are the total wear volume, normal load and the total sliding distance, respectively. ...
On drill bits, the fastest cutting rate is at the circumference, and its rate of travel is equal to the RPM (Revolutions Per Minute) of the bit times the circumference (pi*Diameter). So, the translation between SFM and the RPM speed of a drill bit is: Rotation Speed (RPMs) = (3.82) * SFM / Dia.
