Each mixer truck concrete pump with the number of required calculations

When Concrete mixing plants pump continuous operation, each equipped with the required concrete pump concrete mixer truck number of units, can be calculated as follows:
N = (Q1 / V) * (L / S + Tt)
Where N-number of concrete mixer truck Taiwan (Taiwan);
Q1 an actual average of each concrete pump output volume (m / h);
V-Each concrete mixer machine  capacity (m);
S-Concrete mixer truck average traffic speed (km / h);
L a concrete mixer truck round trip distance (km);
Each concrete mixer truck Tt a total stop time (h).
