7 Concrete pumping operations on site | Concrete pumping

The static pressure due to vertical pumping is therefore 54 x 0-25 = 14 bar. Using the figures already given for output (corrected by work factor), pipeline diameter, theoretical pipeline length and slump, it is possible to arrive at a line pressure figure by using a nomograph (Fig. 96) to which should be added the static pressure.
