A single acting reciprocating pump has a piston of 15 cm diameter and ...
Given data:
Piston diameter (D) = 15 cm
Stroke (L) = 22.5 cm
Speed (N) = 75 rpm
Discharge (Q) = 0.29 m3/min
Suction head (Hs) = 3 m
Delivery head (Hd) = 10 m
We need to calculate the percentage of slip of the pump.
Formulae used:
1. Displacement (D) = πD²L/4
2. Piston speed (V) = 2LN/60
3. Theoretical discharge (Qth) = ADN/60
where A is the area of the piston, A = πD²/4
4. Actual discharge (Qa) = Qth x (1 - Slip/100)
Calculation:
1. Area of the piston (A) = πD²/4 = π(15)²/4 = 176.71 cm²
2. Displacement (D) = πD²L/4 = π(15)²(22.5)/4 = 11909.5 cm³ = 0.0119 m³
3. Piston speed (V) = 2LN/60 = 2(3.14)(15)(75)/60 = 235.62 cm/min = 3.93 cm/s
4. Theoretical discharge (Qth) = ADN/60 = (176.71)(75)/60 = 220.89 cm³/s = 0.22089 m³/min
5. Actual discharge (Qa) = Qth x (1 - Slip/100) = 0.29 m³/min
0.29 = 0.22089 x (1 - Slip/100)
Slip = 2.7344%
Therefore, the percentage of slip of the pump is 2.7344% or approximately 2.7% to 2.8%.
Piston diameter (D) = 15 cm
Stroke (L) = 22.5 cm
Speed (N) = 75 rpm
Discharge (Q) = 0.29 m3/min

Delivery head (Hd) = 10 m

0.29 = 0.22089 x (1 - Slip/100)
Slip = 2.7344%
Therefore, the percentage of slip of the pump is 2.7344% or approximately 2.7% to 2.8%.
