DESIGN, CONSTRUCTION AND PERFORMANCE EVALUATION OF
approaches of known centrifugal pump design methods In this frame, a nonclog type submersible pump that is capable of handling solids, up to a diameter of 80 mm is aimed to be designed The designed pump delivers 100 l/s flow rate against a head of 24 m The rotational speed of the pump is 1000 rpm Design procedure and the important points that differ nonclog pump design from standard There are many different methods used to design ventilation systems, the most common ways being: The tee section at the far end of the main duct causes the air to suddenly divide and change direction There is a high amount of backflow here which again increases the static pressure and reduces the amount of air delivery The high velocity in the main duct which is caused by the sharp Ductwork sizing, calculation and design for efficiency
