Two efficiencies are given in Table 5, the first based on the head 
represented by the difference of level of the suction and discharge 
basins and the second based on the head on the pump as defined 
above. The difference between these two amounted to 2.44 feet in 
the 36-inch unit and 1.82 feet in the 24-inch unit, showing extremely 
bad design of suction and discharge pipes at the ends where they dip
