What can be known directly from the pump nameplate is. A. Rated mass flow rate B. Rated volumetric flow rate C. Maximum allowable suction lift D. Effective power Hint: The pump only specifies the rated volumetric flow rate; the mass flow rate varies depending on the density of the liquid ; The maximum allowable suction height also changes with the suction pipe resistance and the inlet velocity head ; The pump is specified with the shaft power under rated operating conditions, rather than the useful power delivered to the fluid.
