A single triplex pump with Ls 12in Dr 15in pump efficiency

A single triplex pump with (L_s = 12in), (D_r = 1.5in), (pump efficiency = 90%)

the pump is operated at 100 strokes/min with P_discharge of 3428 psi for 4 minutes

the collected mud or drilling fluid collected was 2040 gallons

Determine 1) the pump delivered and 2) the piston diameter DL

H 3 A single tripl pump witn (Ls in the amp is operated at loo shobeslnn, with Pats the collected mud (prilling fluid was for 4 nin Determin D the pump d bp. the Piston d setr PL

Solution

First question is not understandable .

Answer for second question can be derived from the formula

Output in bbl/stk = 0.000243 x (linear diameter in inch )²xstroke length in inch . Here stroke length and discharge is given so the diameter can be found out .
