Counterbalance & Torque Functions
Ideal counterbalance effect, net and peak gearbox torque and polished rod horsepower.
6 functions
PO.RP.Torque.IdealCBE
Calculates ideal counterbalance effect from rod weight and fluid load, [lbf].
PO.RP.Torque.IdealCBE.Loads
Calculates ideal counterbalance effect from PPRL and MPRL, [lbf].
PO.RP.Torque.Adjustment
Calculates counterbalance adjustment needed, [lbf]. Positive = add weight.
PO.RP.Torque.Net
Calculates net gearbox torque at a given crank angle, [lbf.in].
PO.RP.Torque.Peak
Calculates estimated peak net torque (simplified), [lbf.in].
PO.RP.Torque.PRHP
Calculates polished rod horsepower from the dynamometer card work load, [hp].
