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. ...
Predetermined overhead rate = Estimated manufacturing overhead cost/Estimated total units in the allocation base. Predetermined overhead rate = $8,000 / 1,000 hours = $8.00 per direct labor hour. Notice that the formula of predetermined overhead rate is entirely based on estimates.
