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. ...
The third step is to compute the predetermined overhead rate by dividing the estimated total manufacturing overhead costs by the estimated total amount of cost driver or activity base. Common activity bases used in the calculation include direct labor costs, direct labor hours, or machine hours. pre-determined overhead rate is the rate used to apply manufacturing overhead to work-in-process inventory. The pre-determined overhead rate is calculated before the period begins.
