IV. Non – Positive Displacement: These include turbine (or transfer) and centrifugal pumps. They must be primed and traditionally operated at low to medium pressures, although there are miracles available that can go up to 190 psi. Flow from these durable pumps comes from a rotating impeller that feds liquid through the lines instead of pumping per stroke. Therefore if the outlet is closed, the impeller spins harmlessly, so as relief valve is not needed. (Fraser F 1979)

ABSRACT - [ Total Page(s): 1 ]ABSTRACTThe single wheel driven boom sprayer was developed, fabricated and evaluated for its performance at the department of Agricultural and Bio-environmental engineering workshop, Kwara state polytechnic, Ilorin. The spraying performance was carried out at spraying height of 0.5m, 0.6m and 0.7m respectively. The theoretical field capacity CT, the effective field capacity CE and Field efficiency (Å‹) at spraying height of 0.5m are 0.285ha/hr , 0.165ha/hr and 58%, while at spraying hei ...

CHAPTER ONE - [ Total Page(s): 2 ]CHAPTER ONE1.0   IntroductionCrop yield is reduced by mainly due to attack of pest, diseases and weeds. Chemical control is the popular method adopted for controlling most insects, weed and diseases. The chemical are applied either by spraying or dusting. Spraying is one of the most effective and efficient techniques for applying small volume of spray liquid to protect crops. In conventional methods, manually operated low and high volume hydraulic sprayer and power operated hydraulic s ...
