evaluate the water distribution, water pressure, and flow rate. Here you will need to make more assumptions before you can start calculating. The suggested assumption that is needed:
Size of water tank: 2000×3500 mm
Height of water tank: 2,000 mm
Location of water outlet from the water tank: bottom of the water tank
Height of the water inside the water tank: 80% of full storage
Outer diameter of pipe: 32 cm
Inner diameter of pipe: 30 cm
Pipe length: 80 m
Is the water tank open to the atmosphere or is it pressurized
It is pressurized
The water flow rate at the outlet of the shower head:
11.29 sec per 1L which is 0.09 cms
The Reynold Number, friction factor, Loss coefficient of the water flowing
The Pressure Head requires to achieve the measured flow rate (water exiting from shower head)
