# Power

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Power, abbreviated as P or PWR, is the rate of doing work or the rate of using energy per unit time.

## Power formulas

 $$\large{ P = \frac{W}{t} }$$ $$\large{ P = F \; v }$$ $$\large{ P = \frac{F \; d}{t} }$$ $$\large{ P = \Delta p \; Q }$$ $$\large{ P = \gamma \; h_l \; Q }$$

### Where:

$$\large{ P }$$ = power

$$\large{ d }$$ = displacement

$$\large{ F }$$ = force

$$\large{ h_l }$$ = head loss

$$\large{ \Delta p }$$ = pressure drop

$$\large{ \gamma }$$  (Greek symbol gamma) = specific weight

$$\large{ t }$$ = time

$$\large{ v }$$ = velocity

$$\large{ Q }$$ = volumetric flow rate

$$\large{ W }$$ = work
