A pseudorandom number generator includes a unit for providing a number of 2n sequences of numbers, n being greater than or equal to 2. The nozzle includes a seal configured for sealing the lower nozzle plate to the upper nozzle plate, such that the lower and upper impingement surfaces are opposed toward one another, thereby forming a fluid channel between the impingement surfaces, directing pressurized fluid from the at least one fluid intake port to a slotted orifice formed between the opposed lower and upper orifice edges. The comb teeth would be arranged in three rows, each row of teeth having a different height than the other rows.
