4 cast iron sewage pumps

Solved : A centrifugal pump is to discharge 0.118m3/ sec

Question

: A centrifugal pump is to discharge 0.118m3/ sec at a speed of 1450 rpm against a head of 25m. The impeller diameter is 250mm, its width at outlet is 50mm and manometric efficiency is 75%. Determine the vane angle at the outer periphery of the impeller.: A centrifugal pump is to discharge 0.118m3/ sec at a speed of 1450 rpm against a head of 25m.

Answer

: A centrifugal pump is to discharge 0.1 1 8 m 3/ sec at a speed of 1 4 5 0 rpm against a head of 2 5 m. The impeller diameter is 2 5 0 mm, its width at outlet is 5 0 mm and manometric efficiency is 7 5%. Determine the vane angle at the outer periphery of the impeller.: A centrifugal pump is to discharge 0.1 1 8 m 3/ sec at a speed of 1 4 5 0 rpm against a head of 2 5 m.

Step 1

Convert data to SI units: Impeller diameter (D)=250 m m=0.25 m Outlet width (B)=50 m m=0.05 m
