A filtration process is carried out at a constant flow rate until the constant pressure difference reaches 500N/m2. Then the process continues under the conditions of constant pressure difference. If the total time for the filtration is 6400 seconds and one third of the total filtrate is obtained at constant pressure period, calculate the time needed for constant flow rate. 6105 seconds 1477 seconds 1969 seconds 3938 seconds 4923 seconds Bo brak A filtration process is carried out at a constant flow rate until the constant pressure difference reaches 500N/m2.
