Non-thermal dbd plasma disinfection of water usually requires 30 kj/l per 1 log reduction of microorganisms. which power of the plasma device would be required to provide effective sterilization (6 log reduction of microorganisms) of a water stream of 1000 gal/min.

Aplate clutch has a single pair of mating friction surfaces 250-mm od by 175-mm id. the mean value of the coefficient of friction is 0.30, and the actuating force is 4 kn. a) find the maximum pressure and the torque capacity using the uniform-wear model. b) find the maximum pressure and the torque capacity using the uniform-pressure model.

The higher the astm grain-size number, the coarser the grain is. a)-true b)-false

For a gate width of 2 m into the paper, determine the force required to hold the gate abc at its location.
