Model selection principle: calculate ―water consumption of user‖ according to ―number of
people and per capita water consumption‖ and ―water consumption of bathroom accessories‖
respectively, and take the larger value. And then calculate ―water storage capacity of water tank‖,
that is, cubic capacity of water tank.

In this case, there are five persons; one bathtub (with shower), two showers, three
washbasins;
Calculate ―water consumption of user‖ according to ―number of people and per capita water
consumption‖: 5*70=350L;
Calculate ―water consumption of user‖ according to ―water consumption of bathroom
accessories‖: 150+70*2+3*3=299L;
Take simultaneous ultilization rate as 0.7; then total water consumption of user
