In questa Nota viene presentata una soluzione analitica per il moto piano laminare di un fluido di Bingham inizialmente in quiete sottoposto ad un gradiente di pressione costante. Si ottengono espressioni per il calcolo della velocità e dell’ampiezza del nucleo solido centrale in funzione del tempo.
