Abstract


It is revealed that in Coimbatore pumpset market, the coefficient of resistance(K) is more in the case of hemispherical foot valves and it ranges from 1.66 to 5.24 in the case of dominant foot valves like Gowri, Green, DPF and Mohan Kumar brands. In the case of cylindrical foot valves like Kirloskar, Sujala and Jothi brands the resistance is less and it varies from 0.94 to 2.30. Hence cylindrical shape foot valves are more desirable from the energy conservation point of view.
