The crude-oil pumping rig shown is driven at 20 rpm. The inside diameter of the well pipe is 2 in., and the diameter of the pump rod is 0.75 in. The length of the pump rod and the length of the column of oil lifted during the stroke are essentially the same, and equal to 6000 ft. During the downward stroke, a valve at the lower end of the pump rod opens to let a quantity of oil into the well pipe, and he column of oil is then lifted to obtain a discharge into the connecting pipeline. Thus, the amount of oil pumped in a given time depends upon the stroke of the lower end of the pump rod. Knowing that the upper end of the rod at D is essentially sinusoidal with a stroke of 45 in. and the specific weight of crude oil is 56.2 lb/ft3 determine (a) the output of the well in ft3. /min if the shaft is rigid, (b ) the output of the well in ft3 /min if the stiffness of the rod is 2210 N/m, the equivalent mass of the oil and shaft is 290 kg, and damping is negligible.

A machine shaft running at an average speed of 360 r.p.m requires a constant torque of 1.5 kN-m during two revolutions and a constant torque of 400 N-m during next three revolutions and this cycle repeats. Determine the power of the motor required and moment of inertia of a flywheel in order that the total fluctuation of speed shall not exceed 6 percent of mean speed of 320 r.p.m.
Example 18.7. A loaded Porter governor has four links each 250 mm long, two revolving masses each of 3 kg and a central dead weight of mass 20 kg. All the links are attached to respective sleeves at radial distances of 40 mm from the axis of rotation. The masses revolve at a radius of 150 mm at minimum speed and at a radius of 200 mm at maximum speed. Determine the range of speed.

Assuming the resisting torque to be uniform, determine:- (a) the power of the engine when the speed is 150 rpm, (b) the mass moment of inertia of the flywheel if the speed variation is not to exceed ± 0.5% of the mean speed and (c) the angular acceleration of the flywheel when the crank has turned 30° from the i.d.c.
