He isn't. If you pass a fluid with mass through an area at a velocity you get a thing called momentum flux, kg * m/s. This is the same unit as force. If you had a machine in space with a one square meter nozzle spraying a kilogram of water every second out the back at one meter per second in a straight line, the nozzle and other fluid contacting components would experience a net one Newton of force opposite the direction of that flow. If there is nothing to counteract this force then the device will begin accelerating at X meters per second per second where 1 Newton = (mass in kg) * X
