Power

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

 

Power formulas

\(\large{ P = \frac{W}{t}   }\)
\(\large{ P = F \; v }\)
\(\large{ P = \frac{F \; d}{t} }\)
\(\large{ P = \Delta p \; Q }\)
\(\large{ P = \gamma \; h_l \; Q }\)
\(\large{ P = \frac{E}{t}   }\)
\(\large{ P = I^2 \; R   }\)

Where:

\(\large{ P }\) = power

\(\large{ I }\) = current

\(\large{ d }\) = displacement

\(\large{ E }\) = energy

\(\large{ F }\) = force

\(\large{ h_l }\) = head loss

\(\large{ \Delta p }\) = pressure drop

\(\large{ R }\) = resistance

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

\(\large{ t }\) = time

\(\large{ v }\) = velocity

\(\large{ Q }\) = volumetric flow rate

\(\large{ W }\) = work

Solve For:

\(\large{ t = \frac{W}{P}   }\)
\(\large{ W =  P \; t    }\)
