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. ...
However, variable costs applied per unit would be $200 for both the first and the tenth bike. The company's total costs are a combination of the fixed and variable costs. If the bicycle company produced 10 bikes, its total costs would be $1,000 fixed plus $2,000 variable equals $3,000, or $300 per unit.It is very important for small business owners to understand how their various costs respond to changes in the volume of goods or services produced.he reduction in cost per unit is an economy due to scale. Determining the fixed and variable expenses is the first step in performing a break-even analysis. The number of units needed to break even = fixed costs / (price-variable costs per unit).
