## Wastewater Treatment - Mixing Equations

#### Inputs:

 power dissipated (P) wattfoot-pound/secondhorsepowerjoule/secondkilojoule/secondkilowattnewton-meter/second
 water specific weight (γ) newton/meter^3pound/foot^3
 flowrate (Q) meter^3/secondcc/hourcentimeter^3/secondcentimeter^3/hourdeciliter/minutefoot^3/minutefoot^3/secondgallon/minuteliter/dayliter/minuteliter/secondmeter^3/daymeter^3/minutemilliliter/hourmilliliter/minute

#### Conversions:

 power dissipated (P)= 0 = 0foot-pound/second
 water specific weight (γ)= 0 = 0pound/foot^3
 flowrate (Q)= 0 = 0foot^3/second
