Discharge through the reciprocating pump:
The discharge through a single acting reciprocating pump is given as
Q = Volume of water delivered in one revolution × number of revolutions per second
\(Q = V \times \frac{N}{{60}}\)
\(Q = \left( {Area \times Length\;of\;stroke} \right) \times \frac{N}{{60}}\)
\(Q = \left( {A \times L} \right) \times \frac{N}{{60}}\)
\(Q = \frac{{ALN}}{{60}}\)
Calculation:
Given:
A = 0.5 m2, L = 20 cm ⇒ 0.2 m, N = 180 rpm.
Discharge through the reciprocating pump:
\(Q = \frac{{ALN}}{{60}}\)
\(Q = \frac{{0.5\times0.2\times180}}{{60}}=0.3\;m^3/sec\)
Additional Information
For a double-acting reciprocating pump
\(Q = \frac{{2ALN}}{{60}}\)
