QUESTION 03
Consider a triplex pump having 6-in. liners and 11-in. strokes operating at the
MAXIMUM discharge pressure of 3,000 psi. The pump is driven by a 1,500-hp motor.
The mechanical power transfer from the motor to the pump (Em) is 85% and the
volumetric efficiency (Ev) is 97%. Determine:
a) the maximum flowrate (in gpm) that can be used to pump the drilling fluid?
b) the energy transferred (= work done in lbf x ft) by each piston during each
stroke.
