flow youtube

The volume of gas multiplied by the pressure is called the amount of gas, and the amount of gas flowing through a given section is called flow.Flow Q=d (PV)/dt, where p is the pressure, V is volume, T is time.The gas mass flowing through a section of a pipe per unit time is called mass flow rate.According to the ideal gas state equation:Pv=mrt/m (m for gas mass, m for gas molar mass, R for molar gas constant, with a value of 8.3144621[j/(MOL*K)])When

Serie A championship: the task of assigning N m machine. To the number of days each task takes (if not ongoing daily) and can be done on which day tasks. Ask if there is a plan.The typical task (X)----Day (Y) Half of the maximum traffic (because this task is the relationship between days) of the processor control flow.

"Problem Analysis"It is easy to think that it is best to put p on the edge of the maximum flow.So two-point network flow, determine when the maximum flow can be reached.Traffic is not necessarily an integer, so a real number is required, and the integer is WA.Code#include 　　Bzoj 3130 [Sdoi2013] Cost Flow--network flow
