What is the principle of fracturing manifold? The principle of superposition of pressure from multiple fracturing pumps?

The fracturing manifold connects the high-pressure output ends of multiple fracturing trucks together through high-pressure elbows and high-pressure tees. One or more output ports are connected to the wellhead through high-pressure pipelines

The superposition principle of the pressure of multiple fracturing pumps. Since multiple fracturing trucks work at the same time, if the pressure of one truck is lower than the maximum pressure, there will be no output. The displacement is the sum of the instantaneous displacement of all trucks
