A centrifugal pump with a 10 cm suction pipe and a 7.5 cm diameter discharge pipe has a measured capacity of 0.019 m3/s (water), a suction side vacuum of 20 cm mercury (relative density = 13.6) and a discharge pressure of 240345 N/m2 (gage).  The suction and discharge pipes are at the same elevation.  Assuming that the head loss due to friction is negligible, what is the pump power required
