Question: In the city water tower, water is pumped up to a level 25 m above ground in a pressurized tank with air at 125 kPa

In the city water tower, water is pumped up to a level 25 m above ground in a pressurized tank with air at 125 kPa over the water surface. This is illustrated in Fig. P2.84. Assuming the water density is 1000 kg/m3 and standard gravity, find the pressure required to pump more water in at ground level.
