The head required for pumping fluid to a 30 mtr high building depends on the specific gravity and flow rate of the fluid.

• The head required is equal to the sum of the elevation head and friction head.

• Elevation head is the height difference between the pump and the highest point of the building.

• Friction head is the energy loss due to fluid friction in the pipes.

• The specific gravity and flow rate of the fluid affect the friction head.

• The pump should be selected based on the requ...read more
