equal-friction method and in English unit. The total pressure available for the duct system
is 0.12 in. wg (30 Pa), and the loss in total pressure for each diffuser at the specified flow
rate is 0.02 in. wg (5 Pa). Duct fittings are listed in Table 1. Assume the duct dimeter in

A well is going to be installed with a sucker rod pumping unit
a. For the well to be installed with a sucker rod pump calculate the effective plunger
stroke length for a well with a rod pump set at 3600 ft. The well has 3/4-in. sucker
rods and 2 7/8-in. tubing, and the specific gravity of the produced liquid is 0.90. The
pump speed is 12 spm, the plunger is 2 in. in diameter, and the polished rod stroke
length is 64 in.The well is pumped off, so the liquid level is at the pump depth.
b. For well in part a surface production rate the surface with a rod pump having a
volumetric efficiency of 0.8. The oil formation volume factor is 1.2
Give the isometric configuration of the typical piping system of a pump installation using standard
symbols for required valves and fittings. Draw according to valid practice and label the parts.
