Variables Used

Discharge - (Measured in Cubic Meter per Second) - Discharge is the rate of flow of a liquid.
Length of Stroke - (Measured in Meter) - Length of Stroke is the range of movement of piston.
Piston Diameter - (Measured in Meter) - Piston diameter is the value of diameter of a piston of a pump.
Diameter of Piston Rod - (Measured in Meter) - Diameter of piston rod in meters is denoted by the symbol d.
Speed in RPM - Speed in RPM is the number of turns of the object divided by time, specified as revolutions per minute (rpm).

STEP 1: Convert Input(s) to Base Unit

Length of Stroke: 0.88 Meter --> 0.88 Meter No Conversion Required
Piston Diameter: 0.65 Meter --> 0.65 Meter No Conversion Required
Diameter of Piston Rod: 0.2 Meter --> 0.2 Meter No Conversion Required
Speed in RPM: 100 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q = pi/4*L*(2*d_p^2-d^2)*N/60 --> pi/4*0.88*(2*0.65^2-0.2^2)*100/60

Evaluating ... ...

Q = 0.927293431584587

STEP 3: Convert Result to Output's Unit

0.927293431584587 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

0.927293431584587 ≈ 0.927293 Cubic Meter per Second <-- Discharge

What are reciprocating pumps?

The reciprocating pump is a positive displacement pump as it sucks and raises the liquid by actually displacing it with a piston/plunger that executes a reciprocating motion in a closely fitting cylinder. The amount of liquid pumped is equal to the volume displaced by the piston.

How to Calculate Discharge of Double Acting Reciprocating Pump?

Discharge of Double Acting Reciprocating Pump calculator uses Discharge = pi/4*Length of Stroke*(2*Piston Diameter^2-Diameter of Piston Rod^2)*Speed in RPM/60 to calculate the Discharge, Discharge of Double Acting Reciprocating Pump formula is defined as the volumetric flow rate of a double acting reciprocating pump, which is a type of positive displacement pump that uses a piston to move fluid. It measures the pump's ability to transfer fluid, taking into account the piston's movement and the fluid's properties. Discharge is denoted by Q symbol.

How to calculate Discharge of Double Acting Reciprocating Pump using this online calculator? To use this online calculator for Discharge of Double Acting Reciprocating Pump, enter Length of Stroke (L), Piston Diameter (d_p), Diameter of Piston Rod (d) & Speed in RPM (N) and hit the calculate button.
