If thermal spark plasma disinfection of water requires 70 JL

If thermal spark plasma disinfection of water requires 70 J/L, which power of the plasma device would be required to provide disinfection of a water stream of 1000 gal/min.

Solution

1 gallon/minute =0.0630902

Power of plasma device is

P=(70 Joules/Litre) (1000*0.0630902 Litre/second)

P=4416.3 J/s =4416.3 Watts or 4.416 KW
