- 4. "Pump A" usually operates at 1800 rpm using a 6 inch impeller, and its performance is described by the equation h, = 22-0.21 Q?. A homologous pump (i.e., "Pump B") from the same manufacturer operates at 1600 rpm with an 8 inch impeller. What is the performance curve for "Pump B"?arrow_forward3. As shown in the Figure 12, for the variable speed cylinder, a and b are the oil inlet and c is the oil return port. It is already known that D3D200 mm, d1=160 mm and d=D40mm. The flow rate of the hydraulic pump is q-60L/ min. Calculation: the velocity of the piston when the pump only supplies oil to port a and the velocity of the piston when it supplies oil to port a and b at the same time.
